Question

what do you mean by Arithmetic Progression​

Answer 1

Answer:

An Arithmetic progression (AP) or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant. ... The sum of a finite arithmetic progression is called an arithmetic series.

Answer 2

Arithmetic Progression (AP) is a sequence of numbers in order in which the difference of any two consecutive numbers is a constant value. For example, the series of natural numbers: 1, 2, 3, 4, 5, 6,… is an AP, which has a common difference between two successive terms (say 1 and 2) equal to 1 (2 -1).

Formula

• an = a + (n – 1) × d
• S = n/2[2a + (n − 1) × d]
• S = n/2 (first term + last term)
