1 Unit 3A Multiple Choice Review!

2 Rate of Change SLOPE! 𝑦2βˆ’π‘¦1 π‘₯2βˆ’π‘₯1

3 d= common difference (pattern)
EXPLICIT SEQUENCES ARITHMETIC Add/subtract GEOMETRIC multiply an = d(n – 1) + a0 d= common difference (pattern) a0 = first term an = a0(r)n-1 r= common ratio (pattern)

4 an-1 means the previous term
RECUSIVE SEQUENCES ARITHMETIC Add/subtract GEOMETRIC multiply a0 = ____ an = an-1 +d an-1 means the previous term an = ran-1
