Answer:

The three digit numbers which are DIVISIBLE by 9 are 100.

Step-by-step explanation:

Three digit numbers which are divisible by 9 are 108,117,126,… ,999

First term , a = 108, COMMON DIFFERENCE ,d = 117 - 108 = 9 , an = 999

an = a + (n -1)d

999 = 108 + (n - 1) × 9

999 = 108 + 9n - 9

999 = 108 - 9 + 9n

999 = 99 + 9n

999 - 99 = 9n

900 = 9n

n = 900/9

n = 100

Hence,the three digit numbers which are divisible by 9 are 100.
