What 3 consecutive integers have a sum of 51?

Question

I need to know what 3 consecutive integers have a sum of 51

Answer 1

These are fun! What you need to do is express 3 consecutive integers using algebra.

 

If we call the first unknown integer x, then the next one is x+1, and the third is x+2.

 

Now, we add them together:

x + x + 1 + x + 2 = 51

3x + 3 = 51

 

I think you can finish from here!
