    odd integers are 2 apart (1,3,5,7, etc)

    odd integers can be reprsented in the form 2n+1 or 2n-1 where n is an integer

    so 2 consecutive integers can be represented as 2n-1 and 2n+1 (2 apart)

    their sum (add) is 264

    2n-1+2n+1=264

    4n=264

    divide both sides by 4

    n=66

    the numbers are 2n-1 and 2n+1

    2n-1=2 (66) - 1=132-1=131

    2n+1=2 (66) + 1=132+1=133

    the 2 integers rae 131 and 133

    Any integer (not a fraction) that cannot be divided exactly by 2 is an odd integer.

    So, we have (2k + 1) + (2k + 3) = 264, where 2k + 1 and 2k + 3 are the two consecutive positive odd integers (k > 0);

    Then, 4k + 4 = 264;

    4k = 260;

    k = 65;

    2k + 1 = 131;

    2k + 3 = 133;

    The chosen numbers are 131 and 133.
