Question

find the 10th term of the GP

Answer 1

The formula to find nth term in a GP for r>1 is
____________________

tn=(a(r^n)-1)/(r-1)

'r' is the common ratio and 'a' is the first term given

r=tn/t(n-1)

and 't' stands for term

____________________

For n=10

t10=(ar^(10)-1)/(r-1) if r>1

t10=(ar^10-1)/9

Hope it helps you!!!
