To determine the student’s error and write a correct explicit formula.
Given:
The given sequence is:
Calculation:
The student writes an explicit formula for given sequence as:
An explicit formula is a formula that describes the
Now, for the given sequence, the difference between first two terms is
Now, to find the given sequence, subtract
where
Here, the student’s error is the wrong explicit formula for the given sequence, as the value of
