    5 consecutive even integers: n, n+2, n+4, n+6, n+8

    n + (n+2) + (n+4) + (n+6) + (n+8) = 1310

    combine like terms

    5n+20 = 1310

    subtract 20 from each side

    5n = 1290

    divide by 5

    n=258

    n+2 = 260

    n+4=262

    n+6=264

    n+8=266

    Answer: 258,260,262,264,266

    Step-by-step explanation:

    Let the first of these even numbers = n

    The second one is n + 2

    The third one is n + 4

    The fourth one is n + 6

    The fifth one is n + 8

    Their sum is 1310

    Equation

    n + n + 2 + n + 4 + n + 6 + n + 8 = 1310

    Solution

    There are 5 ns.

    The total of the numbers is 2 + 4 + 6 + 8 = 20

    Simplify the given equation

    5n + 20 = 1310 Subtract 20 from both sides.

    5n + 20 - 20 = 1310 - 20 Combine

    5n = 1290 Divide by 5

    5n/5 = 1290/5 Divide

    Answers

    n1 = 258

    n2 = 260

    n3 = 262

    n4 = 264

    n5 = 266

    Check

    The total is 258 + 260 + 262 + 264 + 266 = 1310

    It checks.
