Question

The sum of three consecutive even numbers is 42. Find the numbers.
ter is 140m​

Answer 1

let the numbers be x,x+2,x+4

given= 3x+6=42 x=12

hence the numbers are

12,14,16

Answer 2

Step-by-step explanation:

We can call the lowest integer x, the next integer x+2 (since our integers need to be even) and the third integer x+4. Now we can set up an algebraic equation. 42=x+(x+2)+(x+4).

Combine like terms on the right side,

42= 3x+6.

Subtract 6 from each side

36=3x

Divide each side by 3

x=12, which is our lowest integer.

The next two integers we find with 12+2=14 and 12+4=16. Or just simply take the next two even integers. Thus, 12+14+16=42.

Hope this helps.
