Question

The sum of three consecutive even integers is less than 400.

Answer 1

See below

Explanation:

Let the even integers be:

• 2n, 2n + 2 and 2n + 4

Then we have inequality:

• 2n + 2n + 2 + 2n + 4 < 400
• 6n + 6 < 400
• 6n < 394
• n < 394/6
• n < 65

The numbers are therefore less than 130, 132, 134
