SNAP Series Number Letter and Figure Previous Year Questions

SNAP Series PYQ, free to download as a 27-page PDF. The bank carries 20 solved questions from the 2006 to 2025 papers and takes roughly one day to work through, so treat it as a single focused sitting.

Every question keeps the year it was asked and the options exactly as printed. An answer key follows the questions, then a full worked solution for all 20.

How the Answer Key Was Prepared

Worth stating plainly, because it is unusual. Symbiosis does not release an official answer key for SNAP, and the question papers we work from carry the questions only.

Every answer in this booklet was therefore worked out by our team from the question itself, not copied from an official key. For a series question that bar is specific: a single rule has to reproduce every printed term and land on exactly one option.

Questions where no rule met that bar were left out rather than answered on a guess, which is why 20 of the 41 candidates were published.

Each solution names the rule and shows it holding against the given terms before applying it to the gap.

Why This Set Has No Figure Series

The chapter is named for number, letter and figure series, but only the first two appear here.

Both figure-series questions in the source papers show their sequences as diagrams, and their four options came through the export with no content at all. Printing them would have meant four blank choices under a question that cannot be answered, so they were excluded and the reason recorded.

What the 20 Questions Cover

Series sits inside Analytical and Logical Reasoning, the largest section in SNAP at 25 of the 60 questions. These are among the quickest marks in the paper once the standard rules are recognised.

• Difference series, where the gaps between terms form their own pattern
• Interleaved series, where alternate terms belong to two separate runs
• Letter blocks, where each position advances by its own fixed step
• Wrong-term questions, which ask you to find the one entry that breaks the rule
• Grids and tables, where a rule runs down each column or across each group
• Letters as numbers, where alphabet positions are added or subtracted

The Five Moves That Solve Almost All of Them

Across the 20 questions the same handful of moves keeps working. Naming them makes the section much faster.

• Take differences first; if the gaps form a clean pattern the answer is one step away
• If the gaps look erratic, test whether alternate terms form two separate series
• In letter blocks, treat each position as its own series rather than moving all letters together
• Factorise when terms grow irregularly; factor pairs often reveal a rule the gaps hide
• For wrong-term questions, carry on past the suspect entry using the corrected value and check it still reproduces the later terms

Two Questions Worth Doing First

If time is short, start here. Each teaches a move the rest of the set reuses.

2019, alternating operations. The series 0, 1, 2, 5, 20, 25 alternates adding and multiplying, with the operand rising by one at every step. The printed final term of 157 acts as a free check on any candidate answer, which is exactly how a series question should be verified.

2015, primes hiding in the factors. The terms 2, 6, 20, 42, 110 have gaps of 4, 14, 22 and 68, which reveal nothing at all. Factorising instead gives 1 times 2, 2 times 3, 4 times 5, 6 times 7 and 10 times 11, and the larger factors are the primes in order.

How to Use the Answer Key and Solutions

Attempt the whole set before checking anything. The layout is built so an answer cannot be glimpsed by accident.

• Do all 20 in one timed sitting, allowing about a minute each
• Mark the answer key in one pass, right or wrong only
• Read the solution for every miss and every lucky guess
• Each solution opens with a one-line quick solution, so you can stop there and retry

Traps These Questions Are Built Around

A handful of errors account for most lost marks here, and several questions exist only to catch them.

• Advancing every letter in a block when one position is meant to stay fixed
• Reading gaps of 1, 1, 2, 3 as a simple increase rather than as Fibonacci
• Taking the next term from the wrong run when two series are interleaved
• Judging a triple on its own when the rule only shows up across the parallel groups
• Stopping at the first entry that looks wrong without checking the terms after it still fit

For the rest of the section, the SNAP Blood Relations PYQs cover the other repeated reasoning topic, and the SNAP Averages, Mixtures and Alligation PYQs do the same for quant.
