A sequence starts –3, 1, 5, 9… Homework Help ✎
If you wanted to find the 50th term of the sequence, would an explicit equation or a recursive equation be more useful?
Write the equation in “first term” form as you did in problem 7-108.
What is the 50th term of the sequence?
Write the explicit equation for the sequence 3, 2
, 2 , 2, 1 ... in “first term” form.
Recall the definitions of explicit and recursive equations.
Refer to problem 7-108 to recall what the first term form means.
t(n) = −3 + 4(n − 1)
Insert 50 for n in the equation you found in part (b).
