Complete the Arithmetic Sequence: Finding Missing Terms in 60, 50, ..., 30

To solve this problem, we will identify and use the pattern within the given sequence:

• Step 1: Start with the given numbers $60$ and $50$.
• Step 2: Calculate the difference between these two numbers. We have $60 - 50 = 10$.
• Step 3: Assume this difference will continue throughout the sequence. This assumption is necessary because it suggests a common arithmetic sequence structure.

Following these steps, we can complete the sequence:

First term is $60$.

Second term is $50$.

Based on the assumption of an arithmetic sequence with a common difference of $-10$:

Third term: $50 - 10 = 40$.

Fourth term: $40 - 10 = 30$.

Continuing this pattern:
Fifth term: $30 - 10 = 20$.
Sixth term: $20 - 10 = 10$.

Therefore, the complete sequence is $60, 50, 40, 30, 20, 10$.
