14. How many multiples of 4 lie between 10 and 250?
First multiple of 4 which lie between 10 and 250 is 12.
The last multiple of 4 which lie between 10 and 250 is 248.
Therefore, AP is of the form
First term = a =12
Common difference = d = 4
Using formula , to find nth term of arithmetic progression, we can say that
It means that is the 60th term of AP. In other words, we can say that there are 60 multiples of 4 which lie between and .
