Calculate the Sixth Element of the Sequence: n² - n

To solve this problem, we need to find the 6th term of the sequence defined by $n^2 - n$.

Step 1: Identify the term we need to determine. The problem asks for the 6th element, so $n = 6$.

Step 2: Use the sequence's formula $a_n = n^2 - n$.

Step 3: Substitute $n = 6$ into the formula:

• $a_6 = 6^2 - 6$

Step 4: Calculate $6^2$:

• $6^2 = 36$

Step 5: Subtract 6 from 36:

• $36 - 6 = 30$

Therefore, the value of the 6th element of the sequence is $30$.

Thus, the correct answer is $30$.
