What two consecutive numbers make the sum of 420?
You can write a simple equation: x + (x+1) = 420, where x is the first number. Alternatively, you can make x the second number and write x + (x - 1) = 420. Using the first one, x + x + 1 = 420, so 2x + 1 = 420. 2x = 419 (subtract 1), so x = 209.5. You can check this answer: 209.5 + 210.5 = 420.
