To summarize the process of writing an explicit formula for an arithmetic sequence:
1. Determine if the sequence is arithmetic (Do you add, or subtract, the same amount from one term to the next?)
2. Find the common difference. (The number you add or subtract.)
3. Create an explicit formula using the pattern of the first term added to the product of the common difference and one less than the term number.
I hope my guide has come to your help. God bless and have a nice day ahead!
