Let `(1+x^2^2)^2(1+x)^n = sum _(k=0)^(n+4)a_k x^k. If a_1,a_2,a_3` are in rithmetic progression find n.

(1+x^(2))^(2)(1+x)^(n)=sum_(k=0)^(n+4)a_(k)x^(k). If a_(1),a_(2) anda_(3) are in arithmetic progression,then the possible value/values of n is/are a.5 b.4 c.3 d.2

Let (1+x^(2))^(2)*(1+x)^(n)=sum_(k=0)^(n+4)a_(k)*x^(k) If a_(1),a_(2) and a_(3) are iun AP, find n.
