Heyaa friend ! ☺

>> Here's your answer :

•Formula to find the nth term of a geometric progression :

$t = a {r}^{n - 1}$

•Formula to find sum of n terms of a geometric progression :

$s = a( {r}^{n} - 1) \div r - 1$

where,

t = nth term

a= first term

r= common ratio

n= number of terms

s= sum of all terms of G.P.
