The sum of two consecutive even counting numbers is 66.

Question

A) what are the 2 numbers?

B) if x is the first number what is the sum in terms of x?

Answer 1

Let x be the first number.  The consecutive even counting number is x+2 (because x+1 will be an odd number)

 

B) x + x+2 = 66

 

A) x + x+2 = 66

    2x + 2 = 66

    2x = 64

    x = 32

 

Since x = 32, x+2 = 34.  The two numbers are 32 and 34.  32+34 = 66

Answer 2

n and n + 2 represent the two consecutive even number

n + n + 2 = 66

2n + 2 = 66

2n = 64

 

what are the two numbers?
