12, 15, 18,............ 999
a = 12
d = 3
L = 999
=> a + (n-1)d = 999
=> 12 + (n-1) 3 = 999
=> (n-1) 3 = 987
=> n-1 = 329
=> n = 330
Number of integers between 11 and 1000, that are divisible by 3 = 330

333....1 - 9 -> 3 , 6 , 9 => Three nos in this range = 3
10 - 99 -> 12, 15, 18 …..,99 => Thirty nos in this range { we can get the value of n by using the nth term formula i.e [a + (n-1) * d] } = 30
100–999 -> 102,105,…..,999 => Three hundred nos in this range = 300
total numbers between 1 and 1000 divisible by 3 = 3 + 30 + 300 = 333.
