It could be any number you like since it is always possible to find a polynomial of order 5 that will fit the given 5 numbers and any sixth number.
Fitting the following polynomial, of order 4, shows that the next term should be 110.
Un = (5n4 - 50n3 + 195n2 - 358 + 328)/8 for n = 1, 2, 3, ...
In this series, the 1st, 3rd, and 5th numbers double as they progress, while the 2nd. 4th, and 6th number decrease by 4. That being the case, the next 2 numbers in the series would be 24, 4.
The series alternates between two sequences: one that increases by 1 (11, 12, 13, 14) and another that increases by 1 as well but starts from 2 (2, 3, 4). Following this pattern, the next number in the increasing sequence would be 15, and the next number in the second sequence would be 5. Therefore, the next numbers in the series would be 15 and 5.
Look at the difference between each number and the next number.
The series 1318162119 appears to be a sequence where each number is formed by concatenating the first few even numbers. The pattern is: 2 (2), 4 (4), 6 (6), 8 (8), 10 (10), 12 (12), 14 (14), and 16 (16). Following this pattern, the next even number is 18, which would be represented as "18" in the series. Thus, the next number in the series is 20, resulting in the next sequence being 131816211920.
108
What would be the next number in this series 15 12 13 10 11 8?
The series seems to be "add 3," so the next number in the series would be 12 followed by 15.
The next number in the series 4, 12, 6, 12, 36, 18, 36
The next number in the series 4-12-6-12-36-18-36.. is 108.
The next number is the sequence 236175969, 48, 12 is 236175861.
In this series, the 1st, 3rd, and 5th numbers double as they progress, while the 2nd. 4th, and 6th number decrease by 4. That being the case, the next 2 numbers in the series would be 24, 4.
The series alternates between two sequences: one that increases by 1 (11, 12, 13, 14) and another that increases by 1 as well but starts from 2 (2, 3, 4). Following this pattern, the next number in the increasing sequence would be 15, and the next number in the second sequence would be 5. Therefore, the next numbers in the series would be 15 and 5.
Look at the difference between each number and the next number.
21 - each number in the series increases by the series 1,2,3,4,5.... Whereby 6 and 7 are separated by 1, 7 and 9 are separated by 2, 9 and 12 are separated by 3, 12 and 16 are separated by 4, so the next in the series would be 21 (16 and 21 are separated by 5).
