The naive and obvious approach is to treat it as a solid state black box function which takes an input and produces an output with no context or memory.
This would be f(x) = x * x+1
In the case of 3, this would result in f(3) = 3 * 4 = 12
We don't know that this is accurate though, this could very well also be a series that depends on temporal information from previous answers. The function could also be
f(x) = (10 - number of previous rows) * x
For 3, and being the 5th row as presented, this could result in f(3) = 6 * 3 = 18
There are other potential answers as well. It's a trick question if anyone expects a single answer which is definitely true.
This is why in the real world we use experimentation to determine if our educated guesses get the expected results, then iterate until they do or we make a new discovery to change the guess.
