7
The pattern is two sets of alternating numbers: one counting down, one counting up.
10-1-9-2-8-3-7-4-6-5-6-4-7-3-8-2-9-1-10
You can separate it into two sets of numbers:
10-9-8-7-6-5-4-3-2-1
1-2-3-4-5-6-7-8-9-10
Put these together for the above example.
0.1
10
266
35
25 is the next number that appears in that sequence.
0.1
10
For an integral sequence the next number is 6 (add 5 subtract 7 pattern).
40.
28
Seven (7) is the next number to the sequence in the question.
266
58
it is 7
35
The difference between the numbers is increasing by 2 every time. Therefore, 18 + 9.5 = 27.5 is the next number in the sequence.
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.
