Answer 1

Answer:

300.

Step-by-step explanation:

First term divisible by 3 is 102

Last term divisible by 3 is 999

Common Difference is 3

Let there be n terms. This means that term n of this AP is 999.

Tn = a+(n-1)d

999 = 102+(n-1)3

897 = 3n-3

900 = 3n

n = 300

Thus, there are 300 three digit numbers divisible by 3.
