Find the sum of the arithmetic progression: x-y/x+y, 3x-2y/x+y, 5x-3y/x+y, to n terms

Question

Find the sum of the arithmetic progression:

\(\frac{x-y}{x+y}\), \(\frac{3x-2y}{x+y}\), \(\frac{5x-3y}{x+y}\), to n terms

Answer 1

In an A.P if the first term = a, common difference = d, and if there are n terms.

Then, sum of n terms is given by:

\(\frac{x-y}{x+y}\), \(\frac{3x-2y}{x+y}\), \(\frac{5x-3y}{x+y}\), to n terms
