Question

Hello ya'll. I have a quick question to ask ya'll.
Question: Let be the middle number of three consecutive integers. Write an expression for the sum of these integers.
Sum of the integers = ___

Answer 1

Answer:

$3n$

Step-by-step explanation:

If the initial number is n, one less than n is n - 1, and one more than n is n + 1. so we have:

$n - 1 + n + n + 1=3n$

At first I thought this answer was too easy, so I tried for n is 6.

$3*6=18\\5+6+7=18$

This is really cool! Hope this helps!
