Remark
If you just want one of the numbers, make it x.
Equation
smallest number = x - 4
next number = x - 3
next number = x - 2
next number = x - 1
Largest number = x
Solve
(x - 4) + (x - 3) + (x - 2) + (x - 1) + x = 200 Combine the left terms
5x - 10 = 200 Add 10 to both sides
5x = 200 + 10
5x = 210 Divide by 5
x = 210/5
x = 42 Answer Largest number
