Mathematics
Sequences and series for JEE Main & Advanced — AP, GP, and mixed sums
How series techniques appear inside limits and inequalities on both papers.
On JEE Main
Main tests AP/GP sum formulas, arithmetic-geometric series, and sigma notation in single-correct MCQ format. Method of differences and simple recurrence patterns appear as integer-type questions.
On JEE Advanced
Advanced uses telescoping sums, infinite GP convergence within limits or probability setups, and multi-correct questions where all four options are plausible sum expressions. Partial fraction decomposition of general term is the core tool.
How to practise
Use PracticeJEE's Sequence and Series topic for timed repetition on sum formulas.
