Question

The sum of three consecutive odd numbers is 39. What is the smallest of these numbers?

slove for x​

Answer 1

Explanation:

As, they all are consecutive and odd

The equation = x + (x + 2) + (x + 4) = 39

X represent the first number and also the smallest one

X + 2 is the 2nd number, it's consecutive and odd so we need to add 2

X + 4 is the 3rd number, it's consecutive and odd to (x+2) so we will just add 2 more = x + 2 +2 = x +4

So x + (x + 2) + (x + 4) = 39

3x + 6 = 39

3x = 39 - 6

3x = 33

x = 11

So smallest number = 11

And x + 2 = 11+2 = 13 (second number)

And x + 4 = 11 + 4 = 15 ( third number )

So only because u asked for the smallest

So it's 11
