Question

find the 10th term of gp.if first term is 45 and common ratio is 0.2​

Answer 1

Answer:

9/25×125×125

Step-by-step explanation:

As we know that,

tn=ar^n-1

t10=10th term=ar^10-1=ar^9

As a=first term=45 and r=common ratio=0.2

t10=10th term=45×(2/10)^9

On simplifying we get,

10th term=t10=9/25×125×125
