C Programming

Write a function double sum_sequence(int n) that calculates and returns the sum 1 22 33 455 66 2n1)2n-1 where n is a positive integer argument passed to the function. For example, should return the value ( 1 /1 )-(1/4) + ( 1/27)-(1/256) + ( 1 /3 125)-(1/46656) = 0.7834Your function should be written bearing in mind the limitations on computer-implemented arithmetic that were discussed through the semester. You may not make use of any functions from math.h in this
