This is a geometric progression.
Hello All,
I am just wondering if this following has a formula:
_{i = 0}∑^{k - 1 }X^{i}/Y^{i} = ?
For example, X = 3, and Y = 2, and k = 5
3^{0}/2^{0} + 3^{1}/2^{1} + 3^{2}/2^{2} + 3^{3}/2^{3} + 3^{4}/2^{4} = 1 + 1.5 + 2.25 + 3,375 + 5.0625 = 13.1875;
Any hints?
Thanks!
