The first ten odd numbers
The pattern is... add 7 then subtract 4. The next two numbers would be 45 & 41.
To guess a rule for a pattern, you need several numbers, not just one. Of course, you can invent any rule, for example, "all numbers in the sequence are equal to -4", or some more complicated rule.

Check the differences between consecutive numbers.
The first ten odd numbers
It is not a rule as such; those number are the first 10 prime numbers.
a law!

Each number is decreasing by half.

Hopefully, one of the rules is to put spaces between the numbers so we can discern a pattern.
Check the differences between consecutive numbers.
Homework question: The first numbetr is 4. A rule is multiply by 2 and then subtract 3. What are the first 6 numbers in the pattern
Either the pattern that is given is riddled with errors or it is an extremely complex pattern. The best that I can do is the polynomial of degree 6 as the power of ten. Thus, the nth term is 10Un where Un = 0.0083333n6 - 0.2076923n5 + 1.9855769n4 - 9.1139278n3 + 20.3854604n2 - 20.2990094n + 9.25 and even that is only an approximate fit.
