Notice the following pattern:
2 - 0 = 2
6 - 2 = 4
12 - 6 = 6
20 - 12 = 8
It's reasonable to assume that consecutive terms in the sequence differ by increasing multiples of 2, so that for the next number (call it x) we expect to see
x - 20 = 10 ==> x = 30
and for the number after that (call it y) we would see
y - x = y - 30 = 12 ==> y = 42

Hypothesis testing
For this problem, we need to use the t-student distribution to make inference about the data. We calculate the t-statistics as below:
Using a t-statistics table, or using the function TDIST in Microsoft Excel with 
with two-tailed distribution, we obtain .
