Question

1. Find the 25th term of the ap -5-5by2,05by2




​

Answer 1

Answer:

See, We know that the difference between two consecutive terms differs by a constant D.

So simply ,

let a0 = -5, a1 = -5/2

D = a1 - a0

D = -5/2 - (-5)

= 5/2

Nth term of an AP is given by

an = a0 + (n-1)*D

Given n = 25

a25 = a0 + 24*D

= -5 + (24)*5/2

= 55
