Find the missing number.
If we look carefully, the pattern is:
4-2 = 2
7-4 = 3
11 -7 = 4
16 - 11 = 5
Thus, the differences between the consecutive members of the pattern themselves form a pattern - 2, 3, 4 and 5.
Thus, the next member of the pattern would be obtained by adding 6 to the previous member, 16.
16 + 6 = 22
Thus, the missing number is 22.
