# Fibonacci Sequence

The sequence < un > is defined by the recurrence

Un+1 = 3Un+1\5Un+3

initial condition of u1 = 1:
Need to show un in terms of Fibonacci / Lucas numbers

• Fibonacci Sequence - malformed -

I assume you mean

Un+1 = 3Un + 1/(5Un+3)

since no other interpretation makes any sense.

But that's not an integer sequence. So, how about fixing your typos, using parentheses, and maybe say U<n+1> to avoid mixing subscripts with numeric values?
