The series is a sequence of three numbers, the second number is 3 greater than the first, and the third number is 5 greater than the second. (or 8 greater than the first)
20 + 3 = 23 : 23 + 5 = 28
14 + 3 = 17 : 17 + 5 = 22
11 + 3 = 14........is therefore the next number in the sequence.
59 is the next number in this series.
The next number in the series is 67.
The next number in the series is 13112221.
A single number such as 61205041320 does not make a series.
hat is the next number in the series: 60 30 20 15 12
A single number, such as 12848384 does not make a series.
