Hello all, I have a question in response to the an e-maths question given below:


The product of two consecutive positive even numbers is 60024. What is the smaller of these numbers?

P.S: I do know the workings to this question, but I have a doubt about the workings.


The workings:

Let the smaller no. be p. The other no. be p+2.

And so on....

Why must they use p+2? Can't they use other alternatives like p+1, p+3 etc? Please explain. Thanks so much.
