The pattern is add three and then multiply by three. The next number is 174.

What numbers would you like to be the next three? It is possible to find a polynomial of order 5 that will fit these three numbers and ANY other three numbers. For example, using the positin to value rule given by Un= -112.275n5 + 1,966.25n4 - 12,744.625n3 + 37,416.25n2 - 48,979.6 + 36,525 I can fit the numbers 1, 2 and 3 as the next three. So there are infinitely many possible answers to the question. Using the simplest rule, although the question does not require that, gives Un = 70n + 2001 and that requires the next three numbers to be 2281, 2351, 2421.
Given any number it is easy to find a rule based on a polynomial of order 5+k such that the first five numbers are as listed in the question and the next k are the given "next" numbers. However, use the rule Un = (-6n4 + 83n3 - 411n2 + 874n - 468)/6 Accordingly, the next three numbers are 22, -71, -310
-57The first two numbers in the series has a difference of 89. The next two numbers (209, 129) has a difference of 80. The next two (129,58) has a difference of 71. As you can see the differences change by 9, so the next two numbers in the series (58, -4) has a difference of 62. Following this pattern, the next two numbers in the series will have a difference of 53. So the next number in this series will be (-4-53 = -57).
The sum of the previous two numbers in the series.
This sequence is an arithmetic series that makes use of another series. This sequence advances by adding the series 4, 11, 21, 34, and 50 to the initial terms. This secondary series has a difference of 7, 10, 13 and 16 which advance by terms of 3. So the next three numbers in the primary sequence are 190, 281 and 397.
One possible position to value rule is Un = (20n3 - 90n2 + 160n - 75)/3 Accordingly, the next three numbers are U4 = 325 U5 = 655 U6 = 1165 Alternatively, give my any three numbers that you want as the next three and I will find you a polynomial of order 6 that will fit the 4 given number and the 3 that you specify.
the next three numbers are 180 540 and 1620=)
10 the sequence is 3 numbers miss one, three numbers miss one, etc
