For each of the following sequences, is the common difference equal to 5? A. f(n) = 5n - 3 O Yes O No
B. f(n) = -2n O Yes O No
C. f(n) = 4n - 1 O Yes O No

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
