Question

Find the common difference of the ap for which 25th term is 10more than the 23rd term and the ap is a,a+d,a+ 2d please find

Answer 1

Given

A.P = a , a + d , a + 2d , ...

A.T.Q,

25th term = 23rd term + 10 ---(1)

a + (25-1)d = a + (23-1)d + 10 ( because nth term of an A.P = a + (n-1)d )

a + 24d = a + 22d + 10

24d - 22d = 10

2d = 10

d = 10/2 = 5

Therefore, Common difference of A.P is 5.
