Find the recursive definition of the following sequence (Remember to define the first term t, the recursive rule to find tn, and the value n will start at) 120, 60, 20, 5, 1….

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490
