Question

The nth term of 50, 80, 110 is...

Answer 1

Answer:

$a_n=50+(n-1)30$

Step-by-step explanation:

Given series is,

50,80,110....

First term, a = 50

Common difference, d = 80-50 = 30

We need to find the nth term of the given sequence.

The nth term of an AP is given by :

$a_n=a+(n-1)d$

Put a = 50 and d = 30 in the above formula

$a_n=50+(n-1)30$

Hence, the nth term of the sequence is $a_n=50+(n-1)30$.
