An arithmetic progression is a sequence of numbers in which the difference between any two consecutive terms is constant. For example, the sequence 2, 5, 8, 11, 14 is an arithmetic progression with a common difference of 3.
Geometric Progression (G.P):
A geometric progression is a sequence of numbers in which each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio. For example, the sequence 2, 6, 18, 54, 162 is a geometric progression with a common ratio of 3.
