The sum of 5 consecutive even numbers is 200. what is the fifth number in this sequence

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

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
