How to find total no of 3 digit no when divided by 4 reamains remainder 2

Answer 1

Answer:

225

Step-by-step explanation:

The first 3 digit number to leave remainder 2 when divided by 4 is 102 and the last number to do so is 998.

So, an arithmetic progression can be formed with the first term as 102, last term as 998 and the common difference = 4.

So, the number of terms can be found by using formula

$\frac{l-a}{d} +1 =n$ , where l is the last term and a is  the  first term.

So, number of terms = 225
