The next number is 46. The sequence adds an increasing multiple of 3.
1+3 = 4, 4+6=10, 10+9=19, 19+12=31, and 31+15 = 46.
With 1 as the value for n=1, the value for the nth term is x = 1.5 n² - 1.5n + 1
e.g. the 6th term is 1.5 (6x6) - 1.5 (6) + 1 = 54 - 9 + 1 = 46
48
The nth term is 4n-1 and so the next term will be 19
The pattern is: +11, +15, +19, +23, +27 (4n+7) So, the next number would be: (4*6 + 7) = 24 + 7 = +31 Therefore, the answer is: 105 + 31 = 136
Actually the next number in the sequence is 17 A 19 , 23 , 29 , 31 ,.......... Prim number
The next number in the series is 67.
19 is a prime number and has no factors other than itself and 1. The factors of 10 are 2 and 5.
The next number in the sequence is 27.
10
22
27
the answer is 27
The next number is 27.
27.
This is a peculiar number sequence which follows the following rule: +7, -4, +8, -3, +9, -2... The next few functions would be +10, -1, +11, -0 And thus the next few numbers in the sequence would be 17+10=27, 27-1=26, and so on. The sequence in total goes 2, 9, 5, 13, 10, 19, 17, 27, 26, 37, 37.

The next number is 27. Nice puzzle! The reason is on discussion page, for those who are still working on it.
