43 is a prime number and the next prime number after it is 47
nothing
The difference between the numbers is increasing by 3 each time. Therefore, after a difference of 15 comes a difference of 18, therefore, the next number is 47 + 18 = 65.
It is: 47 because 18+29 = 47
47
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.

65 is the next number
The numbers in the sequence are decreasing by 8 each time. Therefore, the next number in the sequence is 47 - 8 = 39.
The next number is 65, and the number after that would be 86
