Quiz Question

One of a continuing series

mathematics-numbers-01

I stole this from somebody else:

Continue the following number series with the group of numbers below which best continues the series?

1 10 3 9 5 8 7 7 9 6 ? ?

11 5
10 5
10 4
11 6

Provide your answer in the comments section.

Update and Answer

Take a look at the sequence. The first number and every second thereafter increases by 1. The second number, and every second thereafter decreases by two. Therefore the next two number in the sequence are 10 and 4.

Update and Correction

Actually, I got it backward. It’s the odd numbers that increase by 2, and it’s the even numbers that decrease by 1.
