Following are several sets of numbers based on particular (and different) patterns (though not necessarily mathematical patterns), arranged from least difficult to most difficult, and with corresponding point values. The maximum score is 100 - how high can you get? If your answer doesn't match the one I submitted, but makes sense, you may credit yourself the points.

(1):(2 points):(3, 3, 5, 4, 4, 3, 5, 5, 4, 3, 6, 6, 8, ?)

(2):(4 points):(1888, 1892, 1896, 1904, ?)

(3):(5 points):(1, 12, 1, 1, 1, 2, ?)

(4):(6 points):(0, 1, 256, 2187, 4096, 3125, 1296, ?, 64, 9, 1)

(5):(9 points):(1, 22, 12, 5, 26, 16, 7, 28, 18, ?)

(6):(12 points):(2, 4, 5, 6, 9, ?, 15, 21, 26)

(7):(15 points):(0, 4, 7, 0, 2, 4, 6, 8, 0, 1, 3, 4, ?)

(8):(21 points):(6, 10, 14, 15, 21, 22, 26, 33, 34, 35, ?)

(9):(26 points):(0.4330, 1.0000, 1.7205, 2.5981, 3.6339, 4.8284, 6.1818, ?)

Series 7 gives the first number after the decimal point for the square root of the number...

sqrt(1)=1.00 so the 1st number is 0
sqrt(2)=1.41 so the 2nd number is 4
sqrt(3)=1.73 so the 3rd number is 7
sqrt(4)=2.00 so the 4th number is 0
etc, etc
so the ? comes from sqrt(13)=3.60 ie 6

Series 8 comes from multiplying different prime numbers together...

2x3=6
2x5=10
2x7=14
3x5=15
3x7=21
etc,etc
so the ? is 38 (=2x19)
