Question

if 6th term of ap is 22 and 10th term is 38 .find the sum if 15th and 25th term​

Answer 1

Answer:

The answer to this question is 156

Step-by-step explanation:

let the first term of the ap be a and the common difference be d

given that, a+5d = 22 and a+9d = 38

solving these two we get,d=4 and a = 2

Therefore,15th term + 25th term = (a+14d)+(a+24d)

                                                     = 2a+38d = 4+152 = 156
