This series is of the function f(x) = x2+1, starting with x=0.The next number in the series is 26. The number after that is 37.

27, 26, 37, 37

2*2 = 4 + 1 (5) 5*2=10-1 (9) 9*2=18+1 (19) 19*2=38-1 (37) 37*2=74-1 (75) So, its "75" :)

double previous number then alternately either add 1 or deduct 1 9 x 2 = 18 then + 1 = 19 19 x 2 = 38 then - 1 = 37 37 x 2 = 74 then + 1 = 75 75 x 2 = 150 then - 1 = 149 149 x 2 = 298 then + 1 = 299 299 x 2 = 598 then - 1 = 597

The next number in the series 10, -5, 25, -35, 85, -155 is:

202

The amount between each number doubles. Between 16 and 19 = 3 Between 19 and 25 = 6 Between 25 and 37 = 12 Between 37 and 61 = 24 Therefore, the next in the sequence would be: 109

39

53. The sequence starts with one and lists every fourth prime.

These are numbers where after the second number each one is the sum of the previous two. So then you have 23+37 = 60, then 37+60 etc. Eventually you get a series where successive terms are in the same ratio as for the Fibonacci series.

19 23 29 31 37 41 43 47 53 59
