  1. talk like a pirate day! 9.19.22 Take out your notebook for a warm-up. Warm-up Notes: R.O.C Notes: Parallel & Perpendicular Study Time A B Chromebook, Notebook, Pencil, Calculator

  2. Arithmetic Sequences Warm - Up Copy and complete in your Warm-up section. Write the explicit formula: a15= -37 a50 = 103

  3. Arithmetic Sequences Warm - Up Copy and complete in your Warm-up section. Write the explicit formula: a15= -37 a50= 103 First find d: Terms 15 and 50 are 35 apart. (50-15=35) The term values are 140 apart. (103-(-37)=140 Divide to find d: 140/35 = 4 d=4

  4. Warm - Up Copy and complete in your Warm-up section. Write the explicit formula: a15= -37 a50= 103 Next, use the value of d and one of the terms to fill in the formula: an = a1 + d(n - 1) -37 = a1 + 4 (15 - 1) -37 = a1 + 4(14) -37 = a1 + 56 -93 = a1

  5. Warm - Up Copy and complete in your Warm-up section. Write the explicit formula: a9= 7 a20 = -59 Finally, use a1 and d to write and simplify explicit formula: an = a1 + d(n - 1) an = -93 + 4(n - 1) an = -93 + 4n - 4 an = 4n - 97
