Suppose four distinct positive numbers `a_1, a_2, a_3, a_4,` are in G.P. Let `b_1=a_1,b_2=b_1+a_2.b_3=b_2+a_3 and b_4=b_3+a_1.`

Suppose four distinct positive numbers a_1,a_2,a_3,a_4 are in G.P. Let b_1=a_1,b_2=b_1+a_2,b_3=b_2+a_3 and b_4=b_3+a_4 . Statement -1 : The numbers b_1,b_2,b_4 are neither in A.P. nor in G.P. and Statement -2 : The numbers b_1,b_2,b_3,b_4 are in H.P.

Three distinct numbers a_1 , a_2, a_3 are in increasing G.P. a_1^2 + a_2^2 + a_3^2 = 364 and a_1 + a_2 + a_3 = 26 then the value of a_10 if a_n is the n^(th) term of the given G.P. is:
