7, 16, 8, 27, 9, ?

Question

Please help me with this 7, 16, 8, 27, 9, ?

Answer 1

Here are two sequences. The first is the 7, 8, 9. So the next one is 10, then 11.

The second sequence is 16 = 2(8), 27=3(9). The so next one is 40=4(10), then 55 = 5(11).

 

The sequence is 7, 16, 8, 27, 9, 40, 10, 55, 11, 72, 12, 91, 13, 112, 14, ....

Answer 2

Michael, I am not good at sequences, either, but let me help. The parentheses are to separate the operation from the numbers, not to multiply.

 

7 (+ 9) = 16 (- 8) = 8 (+ 19) = 27 (- 18) = 9

 

I bet you can figure it out from here!
