​

two digit number divisible by 30

answer of this question is =30

Answer 2

Answer:

Step-by-step explanation:

The answer of your question is:-

First two digit number divisible by 3 = 12

Last two digit number divisible by 3 = 99

An arithmetic progression (A.P) is a progression in which the difference between two consecutive terms is constant.

A.P = 12,15,18,…,99

here

First term (a) = 12

Common difference (d) = 3

Let us consider there are n numbers then

an = 99

a + (n – 1)d = 99

12 + (n – 1)3 = 99

12 + 3n – 3 = 99

n = 29+1

n = 30

Therefore, Two digit numbers divisible by 3 = 30.
