Answer 2

Question :

The sum of three consecutive odd positive numbers is 105. What is the middle number?

Answer :

The middle number is 35.

Step by step explanation :

Let the first number be x

Then the second number will be x+2 ( since the next number is also odd we will add 2 to x)

Similarly the next number will be x+4

The sum is 105.

That is,

x + x+2 + x+4 = 105

3x + 6 = 105

3x = 105 - 6

3x = 99

x = 99/3

x = 33

The first number is 33

Therefore, middle number = x+2 = 33+2 = 35

And the last number = x+4 = 33+4 = 37
