HP|| relation between AM,GM,HM

The first term of an AP is the same as that of a GP. The common difference of the AP and the common ratio of the GP are each equal to 2. If the sum of the first five terms of each series be the same, find the sixth term of each series.

AP ||GP

If the 2nd, 5th, and 9th terms of a non-euatant AP are in GP, then the common ratio of this GP is

If the 2nd, 5th and 19th terms of a non-constant AP are in GP, then the common ratio of this GP is

If a,b,c are in AP or GP or HP,then (a-b)/(b-c) is equal to
