The sum of three co secutive numbers is 72 what are the smallest of these numbers
dybincka [34]

Step-by-step explanation:

The question above is answered below.

Consecutive numbers are set of numbers that follow one another in ascending or descending order, e.g. 1, 2, 3, 4, 5....

The sum of three consecutive numbers = 72

Let the unknown consecutive numbers be represented by x+1, x+2 and x+3 such that:

(x + 1) + (x + 2) + (x + 3) = 72

Remove the brackets

x + 1 + x + 2 + x + 3 = 72

Collect like terms and simplify

x + x + x + 1 + 2 + 3 = 72

3x + 6 = 72

Make 3x subject of formula by subtracting 6 from both sides

3x + 6 - 6 = 72 - 6

3x = 66

To obtain the value of x, divide through by the coefficient of x, which is 3. Hence;

\frac{3x}{3}  =  \frac{66}{3}

x = 22

Since x = 22,

x + 1 = 22 + 1 = 23

x + 2 = 22 + 2 = 24

x + 3 = 22 + 3 = 25

The smallest of these numbers is 23.

Check,

23 + 24 + 25 = 72
