The trees at a national park have been increasing in numbers. there were 1,000 trees in the first year that the park started tracking them. since then, there have been one fifth as many new trees each year. create the sigma notation showing the infinite growth of the trees and find the sum, if possible. year new trees 1 1000 2 200 3 40 the summation of 1000 times the quantity of one fifth to the i minus 1 power, from i equals 1 to infinity. ; 1250 trees. the summation of 1000 times the quantity of one fifth to the i minus 1 power, from i equals 1 to infinity. ; no sum because series is divergent. the summation of 1000 times the quantity of one fifth to the i power, from i equals 1 to infinity. ; 1250 trees. the summation of 1000 times the quantity of one fifth to the i power, from i equals 1 to infinity. ; no sum because series is divergent.
