Use the formula to evaluate the infinite series. round to the nearest hundredth if necessary. 25+5+1+

Step-by-step explanation:

evaluate the infinite series

25+5+1+ ...

Given series is geometric

Sum of geometric series formula is

Where 'a' is the first term

'r' is the common ratio

to get common ratio divide second term by first term

5/25= 1/5

so a= 25  and r= 1/5
