# How many numbers lie between squares of the following numbers?

(i) 12 and 13 (ii) 25 and 26 (iii) 99 and 100

**Solution:**

'2n' numbers lie between the square of two consecutive numbers n and (n+1).

(i)12 and 13

Here, n = 12. Thus, 2n = 2 × 12 = 24 ,

i.e., 24 numbers lie between (12)^{2} and (13)^{2}

(ii) 25 and 26

Here, n = 25 gives 2 × 25 = 50 , i.e., 50 numbers lie between (25)^{2} and (26)^{2}

(iii) 99 and 100

Here, n = 99 gives 2 × 99 = 198, i.e., 198 numbers between (99)^{2} and (100)^{2}
