Question

The sum of three consecutive odd integers is-219. What is the first number in the set?

Answer 1

-75

Explanation:

Let us consider the first odd number to be 'x'.

Thus:

1. 1st odd number: x
2. 2nd odd number: x+2
3. 3rd odd number: x+3

According to the question, the sum of these three consecutive ODD numbers should be equal to -219

So,

x + x + 2 + x + 4 = -219

3x + 6 = -219

3x = -225

x = -75
