Question

what is AP ? explain and give examples​

Answer 1

Answer:

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).

Answer 2

Arithmetic progression is a sequence of numbers in which the difference of two successive members or the difference of two consecutive terms is a constant

In A.P. ,

Tn or nth term = a+(n-1)*d

Sn or sum of numbers till n = n/2 *[2a+(n-1)*d]
