For this sequence, how can you find the nth term, an, if you know the previous term? A . recursive formula . is a rule for finding a term in a sequence based on the previous term. In general, for a geometric sequence, the recursive formula is an = an – 1 • r. That rule plus the value of the first term (a1) defines the sequence.

Generate terms of a linear sequence using term-to-term and position-to-term definitions of the sequence, on paper and using a spreadsheet or graphical calculator. Generate sequences from practical contexts and describe the general term in simple cases. Begin to use linear expressions to describe the nth term of an arithmetic sequence.
Activity overview:
Problem 2 – Graphically and numerically explore nth term formula. Students explore the variables in the formula of the nth term of an arithmetic sequence by pressing ! and changing the values of the different variables of the sequence. Students are told that . n. is the number of terms, but they should determine the following: a1. is the ...

5. Is the sequence arithmetic, geometric, or neither? Justify your conclusion. 6. Write a rule for the nth term of the sequence. 7. Ignoring physical limitations, could this sequence continue infinitely? In other words, is this the beginning of an infinite sequence? Explain your answer. Remember a series is the sum of the terms of a sequence.
