Question

a,a^2,a^3,a^4,............
find that it is an AP or not with solution thanks ​

Answer 1

No , bro it not in AP because it's common difference it not same

Ie, a^2-a = a(a-1)

And a^3-a^2= a(a^2-a) .

Which is not equal

a(a-1) is not equal to a(a^2-a).

But , actually it is in GP because it common ratio is same .

Ie, r= a^2/a=a.

r = a^3/a^2=a.

Which is same a = a

Therefore it is in GP.
