the average of 4 consecutive even integers is 17. what are the integers and what is the process for solving this problem?

 

n +(n+2) + (n+4) + (n+6)=17 x 4

4n+ 12 = 68 subtract 12 from both sides

4n=56 divide both sides by 4

n=56/4

n=14. So the numbers are:14, 16, 18, 20

14,16,18,and 20. These even numbers are conescutive and average to 17. All you have to do is look at the closest 2 numbers higher and 2 numbers lower than 17!

Let 2N be the first even number

2N + 2 the next

2N + 4 the next

2N + 6  the last   .......so we have

 

Average  =   [sum of the numbers ] / [ how many numbers we have]

 

17  = [ 2N + ( 2N + 2) + ( 2N + 4) + (2N + 6)] /  4      simplify

 

17  =  [ 8N + 12]  / 4    multiply both sides by 4

 

68  = 8N + 12     subtract 12 from both sides

 

56  = 8N    divide both sides by 8

 

7 = N   

 

So the first even number =  2(N)  = 2(7)  = 14

 

Which means that the next three are  16, 18 and 20

 

 

cool cool cool
