59 is the next number in this series.

That number as a whole is not a pattern, but when broken up into the following string of numbers, it is: 1, 2, 4, 7, 11, 16 We can test for several types of patterns if we look for what numbers can be added or subtracted at each step to result in the next number. The string above can be obtained by the following sequential additions: 0, +1, +2, +3, +4, +5 So, each number is the sum of the last number, and an incrementing digit. This makes it a series which can be defined in series notation as: a(n) = a(n-1) + n where n begins at zero. That means that any given number is equal to the previous number, plus it's position in the list. Therefore, the next number, which will be the seventh number in the list (n = 6), will be equal to 16 + 6, which is 22.

The next number in the series is 13112221.

There is no series of number: just one very large number!

One number does not make a sequence (nor a series).

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.

Look at the difference between each number and the next number.
