Question

How to find AP in terms of a and d​

Answer 1

Answer:

The general term (or) nth term of an AP whose first term is a and the common difference is d is found by the formula an=a+(n-1)d. For example, to find the general term (or) nth term of the sequence 6,13,20,27,34, we substitute the first term, a1=6 and the common difference, d=7 in the formula for the nth terms.

Answer 2

An arithmetic progression is a sequence of numbers such that the difference of any two successive members is a constant. The formula for finding the sum of n terms is called Sum=n2(a+l), where, n is the number of terms, a is the first term in the series, l is the last term in the series.

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).
