Answer 1

Answer:

Step-by-step explanation:

Hey mate~!!!!!!!

n=5 terms

Sum= 120 : n/2(2a +(n-1)d)

=5/2(2a+4d)

=5(a+2d)=120

a+2d=24.....................................(1)

Given 5th term is 6 more that sum of first 2 terms :

sum of first 2 terms : a+a+d = 2a+d

5th term : a+ 4d

given : a+4d = 2a+d+6

::::  a-3d=-6.....................................(2)

Solve 1 and 2

a+2d=24

-a+3d=+6

5d=30

d=6

a=12

Thus terms of ap are :  12, 18, 24, 30, 36

Hope this helps!!!!

Thanks!!!
