The pattern is +5, -2.
So it would be:
13+5=18
18-2=16
16+5=21
21-2=19
19+5=24
24
360 8-16
44, 45, 46
16.
what number comes next 1 -8 -16 -24 -33
16 is the next number. All you do is sequentially add the next odd number. Therfore after 16 the next number would be 25... the next 36... the next 49... the next 54...
the next answer would be 1,024
24, they are going up in 3's, 13, 16, 19 and 18, 21 so next number is 24.

The series 1 6 10 13 15 (1+5=6; 6+4=10, 10+3=13; 13+2=15) is completed by 15+1=16. The answer is 16.
