Question

Look at these growing patterns. Find out what to add to each number to get the next one:

0, 2, 6, 12, ______, ______, ______, ______, ______. 

Answer 1

First number: 0

Second number: 2 (i.e. 0 + 2)

Third number: 6 (i.e. 2 + 4)

Fourth number: 12 (i.e. 6 + 6)

Thus, next number will be

12 + 8 = 20

20 + 10 = 30

30 + 12 = 42

42 + 14 = 56

56 + 16 = 72

So, the final pattern will be: 0, 2, 6, 12, 20, 30, 42, 56, 72.
