Web3 apr. 2024 · Sum of Infinite GP Formula Derivation When r < 1 We consider a GP series where the first term is ‘a’ and the common ratio is $r ( r <1)$. Therefore, Multiplying both sides of the equation with the common ratio we get, $Sr=a r+a r^ {2}+a r^ {3}+\ldots (2)$ Subtracting equation (2) from equation (1), we see that $S-S r=a$. Or, S(1-r) = a
WebThe sum of infinite, i.e. the sum of a GP with infinite terms is S∞= a/ (1 – r) such that 0 < r < 1. If three quantities are in GP, then the middle one is called the geometric mean of the other two terms. If a, b and c are three quantities in GP, then and b is the geometric mean of a and c.
