What is an Arithmetic Geometric Progression?

An Arithmetic Geometric Progression or simply AGP, is basically a combination of an Arithmetic Progression and a Geometric Progression as name indicates. Mathematically, an AGP is obtained by taking the product of each term of an AP with the corresponding term of a GP. That is, an AGP is of the form a1b1, a2b2, a3b3,... where a1, a2, a3,... is an AP and b1, b2, b3,... is a GP. If d is the common difference and a is the first term of the AP, and r is the common ratio of the GP then the nth term of the AGP will be (a + (n-1)d)(r^(n-1)).
