The next number in the series is 65. You'll notice that each succeeding number gets a progressive multiple of 3 added to the previous number in the series. The first number is 2, and the next number 5 is 2+(3x1). The next number 11 is 5+(3x2), and so forth. To obtain the number following 47, we simply add to 47 the 6th multiple of 3 (because 47 is the sixth number in the series), that is, 47+(3x6) = 65.
The series seems to be "add 3," so the next number in the series would be 12 followed by 15.
