Sequence And Series IIT JEE

Hello sir, I’m preparing for IIT JEE. Please provide me here notes for sequence and series question in IIT JEE?

[shikha]

In IIT JEE A sequence is a set of values which are in a particular order. In simple words, say that a succession of numbers formed according to some definite rule is called a sequence.

Mathematically, a sequence is defined as a map whose domain is the set of natural numbers and the range may be the set of real numbers or complex numbers.




Here I’m attaching PDF of Questions for series and sequence in JEE:
