To determine the 10th term in the given sequence $0, 1, 2, 9, 8, \ldots$, we need to first identify the pattern or rule governing the sequence.

Observing the terms provided:

1. $a_1 = 0$
2. $a_2 = 1$
3. $a_3 = 2$
4. $a_4 = 9$
5. $a_5 = 8$

One possible way to approach this is to look for a repeating pattern or transformation. Given the first few terms, let's see if there is a pattern for the first few terms:

• The first three terms are $0, 1, 2$, which appear to be simple increments.
• The fourth and fifth terms are $9, 8$, which might suggest a decrement from 9.

Now, checking if there’s any periodic pattern, consider the terms modulo 10:

• $0, 1, 2, 9, 8$

Let's assume the sequence has a period of 5. This implies that every 5 terms, the sequence repeats itself. To determine the 10th term, we consider:

$10 \mod 5 = 0$

Since the 10th term is at a position that is a multiple of 5, it corresponds to the last position of one complete period (which is 5). So,
