What is an arithmetic sequence (a, d, and n)?
What is a finite arithmetic sequence?(2, 5, 8, 11) (Use examples from warm-up)
What is an infinite arithmetic sequence?(3, 6, 9, 12, 15...)
It is harder to locate a specific term in an infinite sequence by counting them. What should we do? ---- Find a general formula!
Given t1=a, t2, and t3:
Generate a formula for t2 and t3 in terms of a(t1) and d
Predict what t4 and t5 will be
Predict what t10 will be
Find a formula for tn (let students guess first)
Tn = t1 + (n - 1)d
= tn-1 + d
Special Cases: If the given terms are not adjacent, how do we find a and d? Example: Given T2, T5, T7
