    10

    10 *1 7*1 = 17

    17* 2 7*2 = 48

    48*3 7*3 = 165

    165*4 7*4 = 688

    688*5 7*5 = 3475

    3475*6 7*6 = 20892



    7 16 41 90 171 ?

    7

    7 + 3^2 = 16

    16 + 5^2 = 41

    41 + 7^2 = 90

    90 + 9^2 = 171

    171 + 11^2 = 292



    12 14 32 102 416 2090 ?

    12

    12*1 + 2 = 14

    14*2 + 4 = 32

    32*3 + 6 = 102

    102*4 + 8 = 416

    416*5 + 10 = 2090


    2090*6 + 12 = 12552



    1 3 24 360 8640 302400 ?

    1

    1 * (4 - 1 ) = 3

    3 * (9 - 1 ) = 24

    24 * ( 16 - 1) = 360

    360 * ( 25 - 1 ) = 8640

    8640 * ( 36 - 1 ) = 302400

    302400 * ( 49 - 1 ) = 14515200
