AI Thread Summary
The discussion revolves around identifying the next number in a sequence derived from the smallest roots of a 9th degree polynomial, with the 9th root being 123456789. Initial terms provided are 3, 7, 14, 23, 36, 49, 66, and 83. A hint suggests that extending the sequence would make it easier to determine the next term. There is a correction regarding the 7th term, with the consensus settling on 104 as the next number. The explanation reveals that the sequence is generated by summing the squares of integers (1, 4, 9, etc.) multiplied by corresponding prime numbers (2, 3, 5, etc.).

These are the smallest 8 roots of a 9th degree polynomial whose 9th root is 123456789
 
It's not quite that arbitrary.

Here's a hint: if I continued the sequence for 20 more terms then it would be much easier to figure out. In fact, from looking at the 10th and 20th terms you could get it almost immediately.

Are you sure 67 is correct for slot 7? I have a formula that gives all of them except it generates 66 for the 7th term.

EDIT: To check, my formula generates 104 for the 9th term.

I agree with Moo, and assume the next term to be 104 [in white].
 
You're right, I did make a mistake. 104 is the answer! Congratulations.

is someone going to show how to do it?
 
Explanation in white: It's the sum of the squares 1, 4, 9, ... with the corresponding primes 2, 3, 5, ...[/color]
