Question

The sum of 4th and 8th terms of an A.P. is 24 and the sum of 6th and 10th terms is 44. Find the A.P.

Answer 1

Step-by-step explanation:

a4+a8=24

=> a+3d+a+7d=24

2a+10d=24

a+5d=12 (eq 1)

Also

a6+a10=44

=> a+5d+a+9d=44

2a+14d=44

=>a+7d=22 (eq 2)

solving eq 1 and 2 we get

a=-13 and d=5

So the ap is

-13,-8,-3....
