and : 19 numbers
by using this formula nth term = a + (n-1)d ,a = first term n = numb of terms d= diff
number of terms diviible by 3 is 33
number of terms diviible by 9 is 11
number of terms diviible by 27 is 3
every number divisible by 9 is divisible by 3 so 33 - 11 = 22 divisible by 3,9
27 contain (27,54,81) which are already included in 3 table so 22-3= 19
