Find the amount of water left in her tank after 1,2,3 and 4 weeks. Explain the amount of water left in the tank after n weeks forms an arithmetic sequence. When does Yafiah’s tank run out of water?

Answer 1

Answer:

Week 1: 2817. Week 2: 2634. Week 3: 2451. Week 4: 2268

An= 2817+(n-1)183 or An= 2817+183(n-1)

At 16 weeks

Step-by-step explanation:

The tank decreases by 183 L every week so just multiply that by the amount of weeks and subtract from the original amount. It runs out at 16 weeks because it becomes a negative amount. I’m not really 100% sure about the equations but I put 2 equations because both can be used.
