Question

Define nth term of an AP

Answer 1

Hey there!

If the first term of an AP is 'a' and its common difference 'd', then its nth term is given by the formula,

An = a + (n-1)d

The nth term of an AP is called its General Term.

If there are n terms in AP, then nth term is known as last term of an AP and it is denoted by l, which is given by formula,

l = a + (n-1)d
where, a is first term & d is common difference
