The sum of 5 consecutive even numbers is 310. What is the third number in this sequence?

A simple way to solve for consecutive numbers is to divide the sum number by the number of numbers needed. So 310 : 5, which equals 62. That is the middle consecutive number.

To find the other 4 numbers, since they are all even, sinply add 2 to the middle number to find one, add 2 to that to find another, subtract 2 from the middle number to fine the third, and subtract 2 from that to find the final one.

62 + 2 = 64

64 + 2 = 66

62 - 2 = 60

60 - 2 = 58

so your numbers are 58, 60, 62, 52, and 66. Together they add up to 310.

(I may have done this a non-standard way, bit it was the way that made the most sense in my head.)
