Answer 2

Step-by-step explanation:

Given:

A4+a8=24.

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

=> 2a+10d=24

=> 2(a+5d)=24

a+5d=24/2=12-----(1)

A6+A10=34

=> a+5d+a+9d=34

=> 2a+14d=34

=> 2(a+7d)=34

a+7d=34/2=17.-----(2)

(2) - (1)

=> a+7d-(a+5d)=17-12

=>a+7d-a-5d=17-12

=> 2d= 5

=>. d=5/2.----(3)

(3) in (1)

=> a+5(5/2)=12

=> 2a+25=12×2=24.

=> 2a=24-25=-1

=> a=-1/2.

The first term of AP is -1/2 and common difference is 5/2.
