Question

5. three consecutive whole numbers are such that the square of the middle number is greater than the product of the other two by 1. find the middle number.

Answer 1

First I took 1, 2, and 3

2² = (1 x 3) + 1

4 = 3 + 1

So here middle number comes 2

then I took  three numbers  2, 3 , 4

3² = (2 x 4) + 1

9 = 8 + 1

So it also comes correct.

So mddle number is 3

Then I tried 3,4,5. It also gives correct answer

Likewise every 3 consicutive you calculate you will get same.
