Question

The sum of three consecutive even integers is 642. What are the integers? (Show your work too please)

Answer 1

Answer:

212,214,216

Step-by-step explanation:

n+n+2+n+4=642

add the n's and 2 and 4

3n+6=642

subtract 6 from both sides

636 divided by 3

you get 212 then add 2 twice.

Answer 2

Answer:

212, 214, 216

Step-by-step explanation:

Basically you can divide 642 by 3 to find the average number of the 3.  get You get 214, so that means 214 + 214 + 214 = 642

We need consecutive EVEN integers though, so you can take the one even BEFORE and then one even AFTER 214

This means 212 and 216 are used as they are 2 before and 2 after, so when added they still total 642.
