If  3 = 18,
4 =  32,
5 = 50,
6 = 72,
7 = 98
Then ,
10 =  ???

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)
