What the next number should be? 11,22,13,26,15,30,17

A. 28

B. 32

C. 34

D. 47

Hello, Draoderick.

The correct answer is C (34).

In the sequence, you first add 11 (11+11=22). Then, after subtracting 9, you add 13 (13+13=26). After subtracting 11, you add 15 (15+15=30). Then 13 is subtracted, so the next step would be to add 17. 17+17=34.

Hope this helps.

Regards,

John

I can help you solve problems involving fractions, decimals, ratios, and algebra. I can teach you how to do math faster, and even in your head. I can teach math definitions, and help you study, if necessary. Please do not ask any graphing, trigonometry, or calculus questions. Try to work through homework questions before asking for assistance.

I routinely process numbers of all kinds in my head, without need of a calculator.**Education/Credentials**

I was an A math student while in high school.
