sequences and series - Evaluate the expression sqrt2sqrt2sqrt2cdots

Is there a way to check whether the expression below converges to a specific number.
222
or in other words does the sequence defined by x0=2 and xn=2xn1 converges?


Trying with a calculator to evaluate an eight-length 2 construct I got 1.9656648865173187 but I couldn't yet confirm convergence.
