Question

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

Answer 1

let the no.are
x,x+2,x+4,x+6,x+8=200
5x+20=200
5x=180
x=180/5
x=36
fifth no.x+8=36+8=44

Answer 2

Define x:

Let the smallest number be x

The other 4 numbers are ( x + 2), ( x + 4), ( x + 6) and (x + 8)

Solve x :

The sum is 200

x + (x + 2) + (x + 4) + (x + 6) + (x + 8) = 200

x + x + 2 + x + 4 + x + 6 + x + 8 = 200

5x + 20 = 200

5x = 180

x = 36

Find the 5th number:

5th number = x + 8 = 36 + 8 = 44

Answer: The fifth number is 44
