    258 is the next number, I think. It’s a sequence, the formula of which is for any number ‘n’,  (n-1)3+(n-1)2+(n-1).

    So we put in 1 to find the first term:
    (1-1)3+(1-1)2+(1-1) = 0+0+0 = 0 = the first term.

    Then we put 2 in to find the second term:
    (2-1)3+(2-1)2+(2-1)= 1 + 1 + 1 = 3

    3 in the find the third term:
    (3-1)3+(3-1)2+(3-1) = 8 + 4 + 2 = 14

     So far we have 0,3, and 14. Now, to find the 7th term, we put in:
    (7-1)3+(7-1)2+(7-1) = 216 + 36 + 6 = 258.

    So we have, 0, 3, 14, 39, 84, 155, 258.
