A marble is rolled down a ramp 3 feet above a table and it was the same height as the table after it rolled 12 inches. After 40 inches, the marble was 7 feet above the table. How would I write this as an equation??

Asequence {an} is defined recursively, with a1 = 1, a2 = 2 and, for n > 2, an = an-1 an-2 . find the term a241

For the rule of 78, for a 12-month period, the last term in the sequence is 12 and the series sums to 78. for an 10 month period, the last term is and the series sum is . for a 15 month period, the last term is and the series sum is . for a 20 month period, the last term is and the series sum is
