Question

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

Answer 1

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

Answer 2

it is not 42 it is 44 just got the answer from my test
