Question

the sum of 5 consecutive even number is 200 what is the fifth number in this seqeunce

Answer 1

Answer: n = 44

Step-by-step explanation:

Let n be the 5th number

n-2 is the 4th

n-4 is the 3rd

n-6 is the 2nd

n-8 is the 1st

this way we shall be solving directly for n.

(n-8)+(n-6)+(n-4)+(n-2)+n = 200

5n-20 = 200

5n = 200 + 20

5n = 220

n = 220/5

n = 44
