Answer

$5\sqrt 2$ and it is arithmetic

Work Step by Step

When we subtract consecutive terms we see we always get a value of $\sqrt 2$. This means that a common difference exists in the sequence. If an common difference exists, by definition, this is an arithmetic sequence. The fifth term is simply adding the square root of 2 to the last term to get $5\sqrt 2$.
