What comes next 5 10 3 8 1?

Answer 1

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

Answer 2

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.

Answer 3

6 comes next. The pattern goes: +5 -7 +5 -7, so then you would +5 and get 6.
