Question

how many two digits number are divisible by 5​

Answer 1

Answer:10, 15,....., 95

As it is in A.P

first term, a = 10;

common difference,d = 5

last term, l = 95

T(l) = a + (n-1)d = 95

=> 10 + (n-1)5 = 95

=> (n-1) = (95-10)/5 = 85/5 = 17

=> n - 1 = 17 => n = 17+1 = 18

There are 18 terms of two digit numbers that are divisible by 5.
