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