The pattern is add three and then multiply by three. The next number is 174.
162, 486, 1458
The sequence appears to consist of numbers formed by concatenating consecutive odd numbers: 1, 4, 9, 16, 25. These numbers are the squares of the first five integers: 1², 2², 3², 4², and 5². The next number in this pattern would be 36, which is 6². Therefore, the next number in the sequence is 36.
If you mean: 1 4 9 16 25 then it is 36
-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).
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.
The sum of the previous two numbers in the series.
the next three numbers are 180 540 and 1620=)
10 the sequence is 3 numbers miss one, three numbers miss one, etc
The difference between the successive numbers is 4. so the next three numbers could be 4, 0 and -4.
Adding 0.6 each time gives 5.2, 5.8 and 6.4 as the next three numbers.
