Given information
The sequence is a decreasing sequence and all its terms lie between the numbers 5 and 8.
Step-by-step explanation
Step 1.
Monotonic Sequence theorem states that every bounded, monotonic sequence is convergent.
Now, all the terms of the sequence lie between the numbers 5 and 8 it implies that is bounded.
Also, is a decreasing sequence implies is monotonic sequence.
Since is bounded and monotonic sequence it implies that is convergent.
Thus, the sequence has a limit.
