Question

NON PERFECT SQUARES NO.S BETWEEN THE SQUARES OF THE NO. [N] AND [N+1] IS; A] NONE B]2 C]INFINITE D]2n

Answer 1

For example, if we need to find the no. of numbers between 50 and 100 (excluding both), we do

(100 - 50) - 1 = 49

We subtract the numbers and further subtract 1.

No. of non perfect squares between n and (n+1) is

(n+1)² - n² - 1

= n² + 1 + 2n - n² - 1

= 2n

SO THE ANSWER IS D]2n
