Question

Question: A swimming pool's water level is being monitored daily. On day 1, the level is 48 inches. On day 2, it is 46 inches. On day 3, it is 44 inches. Identify the common difference and write an explicit formula for the water level after n days. Then find the water level on day 12. Finding the Common Difference and nth Term This lesson walks through identifying the common difference of an arithmetic sequence, building an explicit formula of the form $a_n = a_1 + (n - 1)d$, and using that formula to find any te…
