You can put this solution on YOUR website! .
Select the option for "?" that continues the pattern in each question.
3, -6, 12, 4, 20, ? 3*12 = 36 =  . Following the same pattern, 4*x =  = 400, which gives x = ? = 100.
7, 16, 8, 27, 9, ?
2, 7, 26, 101, 400, ?
7, 21, 8, 72, 9, ?  = 3;  = 9 =  . Following the same pattern,  =  = 27, which gives x = ? = 9*27.
All these/such problems are ALCHEMY and ASTROLOGY and have no any relation to Math (and to the goals of this site).
And my only goal, when I see such problem in the post, is to take it off from the stream flow.
I love to say in such cases: "In this spot the real problem from the real student could be located, who really needs the help".
