I believe @Adam already found the correct solution, but I may have some new ideas concerning the pattern:
2
I’m going to start out with
Now, @Bass’ Perl code
So at least
Therefore

Whenever I see a question like this, I imagine there is unlimited formulas to cover each optional (randomly) selection of those numbers in any direction, and if there isn't any other limiting rules, every answer to that question is correct.
take a look at this

The series should be:
Because:
So the answer is:
Note that:
5
My guess is:
Nevertheless, I don't know where this puzzle comes from but that won't be surprising you are right and your friend may have made a mistake... Unless PSE community finds a simplier solution :)

First, we should determine what the sequence is.
Now, does a 6 ever appear in this sequence?
Quick detour
Back to the show

I'll go with:
Since the sequence seems to be
0
Answer:
Idea similar JonMarkPerry, but slightly different, my guess:
RULES:
1)BOLD NUMBER = BOLD NUMBER +2
2) right number is multiple of first two in a row multiply by number of simple divisors of each number(beginning one, not+2) different from it (EX for 3 is 1, 4 is 2 and 1, for 6 is 3 and 2 and 1 and so on)
3)right number is not bold only ...
0
My solution is...
$l = left$
$r = right$
So the next number is:
(I thought that the bold numbers doesn't matter)
0
My guess:
because:

Solution 1 - expected solution
Solution 2 - uses known Fibonacci list

Step 2:

Answer is:
Giving:
Logic:

It can be assumed that evaluation is left to right (or rather: clockwise), not by precedence rules. Then this reads
and simplifies to

Maybe, oeis will help me..oh no.. this puzzle is spoiled
Answer is:
Key to this is:

There's nothing wrong with @hexomino's answer, but it may be worth adding that
Highbrow explanation for why:
Now,
Note:

The sequence satisfies the recurrence relation
So the next number in the sequence, for example, is
