Question

write the formula of nth term of an A.p and explain its terms​

Answer 1

Step-by-step explanation:

the nth term an = a+ ( n-1) d

Answer 2

Concept

Arithmetic progression is a progression in which each phrase after the first is derived by adding a constant value known as the common difference to the previous term (d).

Given

An Arithmetic progression

Find

We are asked to write the formula of $nth$ term

Solution

Formula of $nth$ term

$a_{n}=a+(n-1)d$

Where $a_{n}$ is the last term

a is the first term

n are the number of terms

and d is the common difference which we can find by subtracting first term from second term
