The next number should be 6.
The pattern is created using two alternating operations: add 5, then subtract seven
Expanding the series a bit...
Number: 5 10 3 8 1 6 -1 4
Difference: 5 -7 5 -7 5 -7 5
Hope that helps
5 10 3 8 1 6 -1
what you need to do is check for the pattern... for 5 to get to 10 5 was added, to get from 10 to 3, 7 was subtracted;
in the same way from 3 to get to 8, 5 was added, then 7 was subtracted to get 1.
6 comes next. The pattern goes: +5 -7 +5 -7, so then you would +5 and get 6.

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.
7
0.1 These are all powers of 10: 10^3 = 1000 10^2 = 100 10^1 = 10 10^0 = 1 10^-1 = 0.1
the answer is 6 and the patern is +5 -7

10
the next number is six (6) the pattern is: add five, subtract seven. 5+5=10 10-7=3 5+3=8 8-7=1 1+5= *6*
11 comes next.
I would say 10 as 3 times the difference between each number is 2 then 3 times 1 would mean 3 times zero difference. Ergo, next number is 10
10.1(+2) 3 (+3) 6 (+4) 10
