The number that comes next in the series 1 2 2 5 3 10 is 7. You get this number by subtracting the number 3 from the number 10.
-31. The rule is t(n) = -2n3 + 12n2 -19n + 14 where n = 1, 2, 3, ...
151. The pattern is the number times 2 plus 1 more than the previous number, starting at 3: 1*2+3=5 :: 5*2+4=14 :: 14*2+5=33 :: 33*2+6=72 :: 72*2+7=151.
The differences between the pairs of numbers up to that point are 31, 32, 33, 34. If the difference between the fifth number and the sixth number is equal to 35, that would make the next number equal to 122 + 243 = 265.
