9 - all the rest are prime
Which one on the numbers doesn't belong in the following series 1 2 5 10 13 26 29 48?
Most probably 48.
Which one of the numbers does not belong in the following series 9 - 7 - 8 - 6 - 7 - 5 - 6 - 3?
3 ((9-2)(7+1)(8-2)(6+1)(7-2)(5+1))
Which one of the letters does not belong in the following series A F H K L N?
N, because it is not in the first half of the alphabet.
Which one on the numbers doesn't belong in the following series 1-2-5-10-13-26-29-48?
The "pairs" in the sequence are doubles of themselves, e.g (1,2) , (5, 10), (13, 26) but for 29 and 48 neither are doubles or halves of each other. However I'm not sure how you know which of 29 or 48 is the odd one out.
