Find the sum of the GP :

x3 + x5 + x7 + …. To n terms


Sum of a G.P. series is represented by the formula, , when r≠1. ‘Sn’ represents the sum of the G.P. series upto nth terms, ‘a’ represents the first term, ‘r’ represents the common ratio and ‘n’ represents the number of terms.


Here,


a = x3


r = (ratio between the n term and n-1 term)


n terms
