For a Sequence
enter the first term,
or the first and
second terms for U.
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
HP 39gII is unable to calculate it automatically.
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
function in Symbolic view, press
another function, then
other functions in terms of their independent variable.
