31 because 3+4=7+4=11+4=15+4 does not equal 31
of course it is! just because its a negative number doesnt mean its not divisible. any number is divisble by itself and the answer is always 1. in this case the answer is negative 1 because the negative needs to appear with one of the answers
Take your pick: 15 is the only number which is a product of 2 primes (3*5). 63 is the only number that is the products of three odd primes (3*3*7) 8 is the only cube number (22) 50 is the only number that is not one less than a square number (15=42-1, 63 = 82-1, 8 = 32-1).
Numerical Answer48 does not belong, because the sequence is (double) then (add 3) and after 256 to 29, the last number should be 58.Spelling Answer2 does not belong, because the rest of the numbers include the letter E when you spell them out in English.
3, they are all squares, three is not.
31 (the rest are all multiples of 3).

48 doesn't belong! 1-2 (+3) 5-10 (+3) 13-26 (+3) 29-48 In each set the 1st number is half of the 2nd exept for the last set.
48 does not belong. The pattern is (times 2) then (plus 3). The last number should be 58.
9 is the only one that isn't prime.
All three numbers belong to the sequence:Un = n^2 + n + 8 for n = 1, 2, 3, ...
If it is not an even number, it is called an odd number. The last digit will be 1, 3, 5, 7 or 9 Example: -3, 1, 7 and 35 are all odd numbers

Ask.com doesnt belong. Yahoo, Gmail, and Hotmail are all email based sites.

20, its a decrease from 30.
