Answer 1

Answer:

Hey!!

Your answer is......

As they are in A. P. so,

a1=4k+8, a2=2k^2+3k+6, a3=3k^2+4k+4

Commom difference =a2-a1

2k^2+3k+6-(4k+8)

2k^2+3k+6-4k-8

2k^2-k-2 eq. 1

Similarly,

Common difference =a3-a2

3k^2+4k+4-(2k^2+3k+6)

3k^2+4k+4-2k^2-3k-6

k^2+k-2 eq. 2

On equating eq. 1 and 2

2k^2-k-2=k^2+k-2

2k^2-k-2-k^2-k+2=0

k^2-2k=0

k(k-2)=0

k=0,k=2.
