There is a series with the length of n (n100), which is defined as an ascending and ordered even number (2, 4, 6, 8, 10,…) starting from 2 ,...), Now you are required to calculate an average by the number of m in order. If there are less than m at the end, calculate the average by the actual number. Program the output
