#### Answer

10, 11, 12, 13, 14
8, 10, 12, 14, 16

#### Work Step by Step

I started with 12. Then, I subtracted 1, and subtracted 1 again. After that, I added 1 to 12, and added 1 again. I took all the sums, put them in numerical order, and got my sequence. For the second sequence, I repeated the above steps but I added/subtracted 2 instead of 1.
