Then, k th term from the end of the GP will be T k = ar n-k. If a is the first term and r is the common ratio respectively of a finite GP with n terms. If a, b and c are three quantities in GP, then and b is the geometric mean of a and c then, the sum of a GP with infinite terms is S ∞= a/(1 – r) such that 0 < r < 1.įor three quantities in GP, the middle quantity is called the Geometric Mean of the other two terms. n th term from the end of the GP with the last term l and common ratio r = l/.The formula to calculate the sum of the first n terms of a GP is given by: Here, a is the first term and r is the common ratio. The general form of terms of a GP is a, ar, ar2, ar3, and so on. The list of formulas related to GP is given below which will help in solving different types of problems. is a sequence that contains infinite terms in a sequence and can be written as a, ar, ar 2, ar 3,……ar n-1, ar n……, i.e. ISRO CS Syllabus for Scientist/Engineer ExamĮxamples of Finite GP is 1, 2, 4, 8, 16,……512 Infinite Geometric Progression.ISRO CS Original Papers and Official Keys.The first term is 2, and the common ratio is 6.
