Question: Write a rule for the nth term of the sequence. Use your rule to find a100.–8, 9, 26, 43, 60, . . . I don't get the whole thing about writing rules. What does it mean?
It wants you to find a pattern to the values above. Kind of like if you saw a table with these values, how are you getting from one to the next. |dw:1358368018499:dw|
That is something of how the table would look. Although it's probably easier to just use a basic function and then go from there. In this case you can see between each value (without using the table) that you are adding 17 to get the next value. so the basic "rule" or function for the values is. n+17
that means starting from the initial value, adding 17 will give you the next and so forth. BUT you must insert the previous value in this case for the pattern to stay constant.
