hey..
let a=a1
a^2=a2
a^3=a3
a^4=a4
r=a2/a1
=a^2/a
=a
r=a3/a2
=a^3/a^2
=a
r=a4/a3
=a^4/a^3
=a
so the common ratio is same..thus it forms G.P

let a=a1
a^2=a2
a^3=a3
a^4=a4
r1=a2/a1
a^2/a^1
=a
r2= a3/a2
a^3/a^2
=a
r3=a4/a3
a^4/a^3
= a
since in GP series common ratios are same which is in this series also therefore it is proved that this series is a GP series.
