Answer: the page numbers are 253 & 254

Explanation:

Let the lower page number be x.

The the higher page number is x+1

Added together, they are 507, so ...

x + (x + 1) = 507

2x + 1 = 507

2x = 506

x = 253

x+1 = 254

Check answer: 250+3 + 250+4 = 250+250 + 3+4 = 500 +7 = 507 - -Checks!

Hope this helps!
