Answer 2

ANSWER:

• Number of terms = 128

GIVEN:

• Three digit number are divisible by 7.

TO FIND:

• Number of 3 digits number Divisible by 7.

SOLUTION:

First 3 digit number Divisible by 7 is 105.

Last 3 digits number Divisible by 7 is 994.

So the required series :

105 , 112 , 119 .......... 994.

Here:

First term (a) = 105.

Common difference (d) = 7.

Last term (l) = 994.

Formula:

nth term = a+(n-1)d

Putting the values in the formula:

=> 994 = 105 +(n-1)7

=> 994-105 = (n-1)7

=> 889 = 7(n-1)

=> 889/7 = n-1

=> 127 = n-1

=> 127+1 = n

=> 128 = n

Number of terms = 128.
