Then define the nth
term of the
sequence in terms of N or the prior terms, U(N–1)
and/or U(N–2). The expressions should produce
real-valued sequences with integer domains. Or
define the Nth term as a non-recursive expression
in terms of N only.
Note: you will have to enter the second term if the

Typically if Ux(N) depends on Ux(N–2) then you
must enter Ux(2).
In the Symbolic view, a variable is a symbol only, and
does not represent one specific value. To evaluate a
