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.
next prime number after 31 = 37
It is: 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" :)
37
27, 26, 37, 37
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.
202
The next number in the series 10, -5, 25, -35, 85, -155 is:
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
The next prime number after 31 is 37.
39
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
53. The sequence starts with one and lists every fourth prime.
