Homework 5.4 #2

Write the explicit rule for this situation.

• f(n) = 35 + 3(n − 1)
• f(n) = 35 −3(n − 1)
• f(n) = 3 + 35(n − 1)
• f(n) = −3 + 35(n − 1)

Select the explicit rule that represents the sequence.

• a_n = 14(-3)(n - 1)

• a_n = 3 + (n - 1)(14)

• a_n = 14 + (n - 1)(-3)

• a_n = -3 + (n - 1)(14)
