They are -30 and -147.
My rule is
Un = (-25n4 + 326n3 - 1487n2 + 2746n - 1680)/24 for n = 1, 2, 3, ...

Two consecutive numbers are added together to get the next one. 1,1,2,3,5,8,13...
That's a Fibonacci sequence. After the first two numbers, each new number is the sum of the previous two numbers. The next number in that sequence would be 13.
162 and 486 the pattern is that the next number is three times the previous number.

One number does not make a pattern - no matter how big it is. No pattern so no next numbers in the pattern.

The next three numbers are: 87, 141, 228. Each number in the sequence after the first two is the sum of the previous two numbers. This is a variation of the Fibonacci sequence which starts with 1, 1, ... (and then continues ..., 2, 3, 5, 8, 13, ...).
what would be the next two numbers in this pattern 5 -30 180 -1080

13, 21 - it is the Fibonacci sequence
The next two numbers in the sequence are... 45 & 54.
