Having a bit of trouble with this question.
Any help would be greatly appreciated.

Can you add four consecutive whole numbers (e.g., 7, 8, 9, 10) to produce a
multiple of 4? Show using algebra and explain your answer well.

Alright! High school algebra- one I just might be able to do!
The key word here is consecutive. Let x be the smallest of the four numbers. Then the other three are x+ 1, x+ 2, and x+ 3. Add x+ (x+1)+ (x+ 2)+ (x+ 3). What do you get? What does x have to be for that to be a multiple of 4?
