    3-4: 14 = 32
    4-5: 18 (plus 4) = 32+18 = 50
    5-6: 22 (plus 4) = 50 +22 = 72
    6-7: 26 (plus 4) = 72 + 26 = 98
    7-8: 30 (plus 4) = 128
    8-9: 34 (plus 4) = 162
    9-10: 38 (plus 4) = 190

    ??? = 190

    I'd say that 10 = 200. As the first number of each answer needs to be multiplied by the next even number in succession to the last. Or words to that effect lol.

    I will say the answer is 200 if I'm following the multiplication pattern that has been established.

    Following this sequence,
    3 x 6 = 18
    4 x 8 = 32
    5 x 10 = 50
    6 x 12 = 72
    7 x 14 = 98
    8 x 16 = 128
    9 x 18 = 162
    then 10 x 20 = 200.

    10 = 20

    3 = 18  (3 x 6)
    4 = 32 ( 4 x 8)
    5 = 50  (5 x 10)
    6 = 72 ( 6 x 12)
    7 = 98 (7 x 14)
    8 =      (8 x 16)
    9 =      (9 x 18)
    10 = 200 ( 10 x 20)
