Question

The population of a local species of flies can be found using an infinite geometric series where a1 = 940 and the common ratio is one fifth. Write the sum in sigma notation, and calculate the sum (if possible) that will be the upper limit of this population.

Answer 1

I got the summation of 940 times one fifth to the i power, from i equals 1 to infinity. ; the sum is 1,175

Answer 2

Yes it's correct, but the sum would start at i=0
