Here's how the sequence should go (first 4 terms):
1.....2.....3.....4
7, 7/3, 7/9, 7/27
Notice how I started with 7 and multiplied it by the common ratio (1/3) to determine the second term. Multiplying the latter by 1/3 again gives you the next term, and so on.
Use the pattern to find the sixth term.
A table of values of a linear function is shown below. Find the output when the input is n.
Input 1 2 3 4 n
Output 2 1 0 -1 ?
