How can I simplify a series like this one in order to have an function to easily calculate $u_x$ ?
$$(u_0+1000) \times 1,1 = u_1 $$ $$(u_1+1000)\times1,1 = u_2 $$ $$(u_2+1000)\times1,1 = u_3$$
Moreover what kind of series it is ?
I looked for a geometric series and arithmetico-geometric series but it doesn't seem that are the one I'm looking for.
