WebFormulas of Geometric Progression (G.P) Suppose, if ‘a’ is the first term and ‘r’ be the common ration, then. Formula for nth term of GP = a r n-1; Geometric mean = nth root of the product of ‘n’ terms in the GP. Formula to find the geometric mean between two quantities a and b = \sqrt{ab} Formula to find the sum of the number of ... WebProperties of Geometric Progression. If ‘a’ is the first term, r is the common ratio of a finite G.P. consisting of m terms, then the nth term from the end will be = a rm-n. Reciprocal of all the term in G.P are also considered in the form of G.P. When all terms is GP raised to same power, the new series of geometric progression is form.
