The sum of a GP is the sum of a few or all terms of a geometric progression. GP sum is calculated by one of the following formulas:Sum of n terms of GP, Sn = a(1 - rn) / (1 - r), when r ≠ 1Sum of infinite terms of GP, Sn = a / (1 - r), when |r| < 1Here, 'a' is the first term and 'r' is the common ratio of GP. A series of numbers obtained by multiplying or dividing each preceding term, such that there is a common ratio between the terms (that is not equal to 0) is the geometric progression and the sum of all these terms formed so is the sum of geometric progression (GP).
