the average of 4 consecutive even integers is 17. Is there a solution, and if there is what are the integers and what is the process for solving this problem?
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
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
