Key Points: Properties of G.P.
-
Ratio between consecutive terms is constant
-
If a, b, c are in G.P. → b2 = ac
-
Multiplying or dividing all terms by the same non-zero number gives a G.P.
-
Reciprocals of terms of a G.P. also form a G.P.
-
Corresponding terms of two G.P.s, when multiplied or divided, give another G.P.
Shortcut:
Three terms of a G.P. →\[\frac{a}{r}\], a, ar
