Consider the following cash flows, each occurring at the end of the year indicated:

Year Cash Flow

$1$ $$1,000$

$2$ $$4,000$

$3$ $$1,000$

$4$ x

If the present value of all cash flows is $$3,798\mathrm{.}93,$ and the required rate of return is $5\%$ per year, what is the value of the missing cash flow x$?$ Do not round intermediate results and round your answer to the nearest whole dollar. Do not enter a $"$$$"$ sign, and use a $"-"$ sign if your answer is negative.
