Question

solve plz...............​

Answer 1

Answer:

13 numbers are divisible by 7

Answer 2

Given:

a ( first term ) = 14 ( lowest two digit number which is divisible by 7 )

d ( common difference ) = 7

an ( last term ) = 98 ( highest two digit number which is divisible by 7 )

To Find:

n ( total two digit numbers which are divisible by 7 )

Formula:

an = a + ( n - 1 )d

Solution:

By putting the respected values, we get

98 = 14 + ( n - 1 )7

or, 98 - 14 = ( n - 1 )7

or, 84 / 7 = n - 1

or, 12 + 1 = n

or, 13 = n

Answer:

Total two digit numbers which are divisible by 7 are 13.
