Attempt any five

A sequence is a collection of numbers arranged in a definite order according to some definite rule.

Given:

Here, t₁ is the first term for n = 1

And, t₂ is the second term for n = 2

& the sum of the terms is given by S_n.

Hence, S_n is the sum of first n terms.

=

Now, second term is given as : t₂ = S₂– S₁

⇒ t₂

Also, Third Term = S₃ – S₂

Hence, the sequence is
