The next number in the sequence 3, 6, 11, 18, 27,........ is:

Question: The next number in the sequence 3, 6, 11, 18, 27,........ is:

Solution:
The difference between the first two numbers is 3 (6 - 3 = 3)
The difference between the next two numbers is 5 (11 - 6 = 5)
The difference between the next two numbers is 7 (18 - 11 = 7)
The difference between the next two numbers is 9 (27 - 18 = 9)
The difference between the next two numbers is 11 (38 - 27 = 11)
So, the next number should be 38.
