An arithmetic progression is a sequence of numbers in which each successive term is a sum of its preceding term and a fixed number.
a a+d a+2d a+3d ….....nth term
here d= common difference
A geometric progression is a sequence where every term bears a constant ratio to its preceding term.
a ar ar2 ar3......arn-1
here r= common ratio
