Number Series. Give the next number in each of these 4 series and state why you arrived at that number?
2, 3, 4, 6, 8, 12, 14, 18, 20, ?
3, 6, 13, 26, 33, 66, ?
9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, ?
15, 15, 13, 13, 13, 14, ?
No apologies for the difficulty of No 4.
Good luck.

This is too difficult. I think I’ve got 1 so far.
3, 6, 13, 26, 33, 66, ? NEXT NUMBER 73 (double then add 7)

2, 3, 4, 6, 8, 12, 14, 18, 20, ? 22 (the missing numbers are 5, 7, 9, 10, 11, 13, 15, 16, 17, 19. The gaps between these numbers read 2, 2, 1, 1, 2, 2, 1, 1, 2. Two 2’s followed by two 1’s so to complete the sequence a gap of 2 is required. Next number is 22. God that was difficult!! Hope you followed my explanation)

9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, ? 30 (These are composite numbers. 30 is next)

Answer to 2nd series is correct.
Answer to 1st series wrong (although your logic stands up there is a simpler answer)
Answer to 3rd series is correct.
Good luck with 4th series

No 1 is 24
It's a sequence of Prime numbers plus 1
No4 ???

You'd have thought he'd give some sort of clue. My head hurts.

Tell me about it Zippy. I can’t even think of a starting point.
I’ve given up now. I reckon it will be something that abstract it is almost impossible to work out.

Like the logic TBG. That’s what I call 9-5er logic!! Can’t be beaten…..can’t be explained!!!

OK you've done good so far. Also noticed that there was too many 13s in the series so I taken one out. It won't really help you though so here is the clue that zippy asked for.
Each number in the 4th series is the sum of 2 numbers each of which also belong to a series.

Answer to 4th series:
The numbers are the sum of 2 other series. One is a decending series of primes 13, 11, 7, 5, 3, 2 added to an ascending series of even numbers 2, 4, 6, 8, 10, 12. Thus the series 15, 15, 13, 13, 13, 12 is produced. The next number is therefore 1+14=15.
SORREE.

Jesus wept. Not happy at that!!
I suppose you did warn us it was difficult. I don’t see how anyone could work that out!!
