Question

Help me please...
your given that: u(base 1)=1 and u(base n+1)=u(base n)/1+u(base n)

Find the values of U (base 2), U(base 3) and U (base 4). give your answers as a fraction
and please be so nice to explain it

Answer 1

that looks like recursion formulas

Answer 2

\[U_{n+1} = \frac{U_{n}}{1+U_{n}}\]

Answer 3

U{1} = 1 so....

U{2} = 1/(1+1) = 1/2

U{3} = (1/2)/(1+(1/2)) = 1/3

U{4} = [1/3]/ [1+(1/3)] = 1/4

Answer 4

you just keep reiterating the past amount to find the present amount

Answer 5

'btm' works with themand his material calls them difference equations..... which seems an archaic term

Answer 6

thank you very much
