================
This type of problem is worthless. An argument can be made for more than one next number.
7,16,8,27,9,?
---
The odd # elements are 7, 8 & 9
The even are 16 & 27. A difference of 11 --> 38 for #3.
#1 is 4^2, #2 is 3^3 --> 2^4 for #3 = 16
---
#1 is 2^4, #2 is 3^3 --> 2^4 for #3 = also 16
---
#1 is 16^1, #2 is 3^3 --> (-10)^5 = -100,000
=============
It's ambiguous, and useless. Nothing to learn here, except that some people who don't know what they're doing write math books.
