Question

What is the next value?
0 3 8 15 24 35.

Answer 1

0+3=3
3+5=8
8+7=15
15+9=24
24+11=33
33+13=48 next

Answer 2

Look at the differences of each of the values. 3-0 = 3, 8-3 = 5, 15-8 = 7. The differences increase by 2, or you can look at it as increasing each odd number.

Take the last value, 35, and add 35-24= 11 the next odd number, 13, to it. 35+13= 48,
