Question

The lowest and leftmost note on a piano keyboard is an A. The next lowest A is seven white keys to the right. This pattern continues. Write an explicit formula for an arithmetic sequence to represent the position of each A key on the piano, counting from the left. If a piano has 52 white keys, in what position is the key that plays the highest A?

Answer 1

Answer: Not sure but this may help!

Step-by-step explanation:

A = 7 —>

52 keys which means A is 7 keys to the right and there is about 7 A keys. 52 divided by 7 = around 7. I don’t know the question but I need points!
