Step-by-step explanation:

The smallest 2 digit no is 14

And largest 2 digit no is 98

So. It is the form of AP

The series is 14 ,21,28,………98

T=a+(n-1)d

T=98 , a=14 ,d=7

98=14+(n-1)7

98=14+7N-7

98=7+7n

98-7=7n

91=7n

91÷7=n

We need to find number of two digit numbers which are divisible by 7.

99/7 = 14.1428...

Thus 14 * 7 = 98 which is the highest two digit number.

14 is the least 2 digit number divisible by 7.

14 = 2* 7

Thus the two digit numbers divisible by 7 are:

2 * 7, 3 * 7,4 * 7, 5 * 7,.... 14 * 7.

Thus number of two digit numbers divisible by 7 is 13.

Originally Answered: How many numbers of two digits are divisible by 7?

The smallest two-digit number divisible by 7 = 14 and the largest two-digit number divisible by 7 = 98. So, it turns out to be an AP series:

14, 21, 28, ……………, 98.

14 + (n - 1)*7 = 98

7n = 91

n = 13

So, the answer is 13.
