Solution: The value of a term depends on the value of the previous term as shown in the formula. So value of 5th term depends on value of 4th term which itself depends on value of 3rd term which further depends on value of the 2nd term. So we need to find all these values to reach at the 5th term.
f(1) = 200
f(n) = 2 x f(n-1) So,
f(2) = 2 x f(2-1) = 2 x f(1) = 2 x 200 = 400
f(3) = 2 x f(3-1) = 2 x f(2) = 2 x 400 = 800
f(4) = 2 x f(4-1) = 2 x f(3) = 2 x 800 = 1600
f(5) = 2 x f(5-1) = 2 x f(4) = 2 x 1600 = 3200
So the 5th term of the given recursive function is 3200.
This is because no matter what m is, the cost of one ticket is $2. So, in order to figure out what the cost of all the tickets are, you must multiply to get your answer. Therefore, your expression or equation is 2 m.
