Answer:
Step-by-step explanation:
The first 2-digit number divisible by 6 is 12.
And the last 2-digit number divisible by 6 is 96.
The AP is -
12, 18, 24, ..., 96
d = 18 - 12
= 6
an = a + (n - 1)d
96 = 12 + (n - 1)6
= 12 + 6n - 6
= 6 + 6n
6(1 + n) = 96
1 + n = 16
n = 15
Therefore, 15 2-digit numbers are divisible by 6.
