Question

The sum of 3 consecutive evennumbers is 78.Write the variable representation for each ofthe three numbers in this sequence.

Answer 1

we know that the sum of three consecutive numbers is equal to 78 so:

`a+b+c=78`

where a b and c are consecutive even number so we can rewrite the equation in term of a single variable:

`x+(x+2)+(x+4)=78`

So now we have a equation where we can solve the problem
