Given the sequence: 25, 21, 17, 13,... Write the explicit equation that models the sequence. (Hint: Use your calculators.)

• a_n = 4n + 29

• a_n = -4n + 25

• a_n = -4n + 29

• a_n = 4n + 25

Given the sequence: 25, 21, 17, 13,... Write the explicit equation that models the sequence.

• a_n = 4n + 25

Write the explicit formula for the geometric sequence.
