Determine whether the sequence is increasing, decreasing, or not monotonic. Is the sequence bounded? a. an = 1 / 2n + 3 b. an = n(- 1)n c. an = n / n2 + 1
Determine whether the sequence is increasing, decreasing, or not monotonic. Is the sequence bounded?
a. an = 1 / 2n + 3
b. an = n(- 1)n
c. an = n / n2 + 1
a. an = 1 / 2n + 3
b. an = n(- 1)n
c. an = n / n2 + 1

Answer
a. a n = 1 / 2 n + 3 is decreasing since a n +l = 1/2( n + 1) + 3 = 1/2 n + 5 < 1/2 n + 3 = a …View the full answer
