• You can use only one variable in the function for input sequence {
a
k
}.
• Input integers only for the initial term of sequence {
a
k
} and last term of sequence
{
a
k
}.
• Input of
n
and the closing parentheses can be omitted. If you omit
n
, the calcula-
tor automatically uses
n
= 1.

Calculation Precautions
• Make sure that the value used as the final term
β
is greater than the value used
as the initial term
α
. Otherwise, an Ma ERROR will occur.
• To interrupt an ongoing
Σ
calculation (indicated when the cursor is not on the dis-
play), press the
A
key.
