What is the next number in the following series: 15, 12, 17, 14, 19, a. 14 b. 13 c. 16 d. 15 (explanation would be appreciated)

to get from 15 to 12 you subtract 3

to get from 12 to 17 you add 5

to get from 17 to 14 you subtract 3

to get from 14 to 19 you add 5

so, based on this pattern you can assume that you can get the next number by subtracting 3 from 19. so that means you'd do 19-3 and you would get 16 as your answer.

your answer is C.16

Hope this helps :)
