Answer 2

First term between 200 and 300 which is divisible by 13, a = 208

Last term between 200 and 300 which is divisible by 13, an = 299

Common difference, d = 13

We know that an = a + ( n - 1 )d

By putting the respected values, we get

299 = 208 + ( n - 1 ) 13

or, 299 - 208 = ( n - 1 ) 13

or, 91 / 13 = n - 1

or, 7 + 1 = n

or, 8 = n

Answer:

(c) 8

There are 8 terms between 200 and 300 which are divisible by 13.
