37. Explain why or why not Determine whether the following statements are true and give an explanation or
counterexample.
a. Suppose 0 < ak <bk. If Σak converges, then Σb converges.
b. Suppose 0 < a <bk. If Σak diverges, then Σb diverges.
c. Suppose 0 <bk <ck <ak. If Σak converges, then bk and Σck converge.

d. When applying the Limit Comparison Test, an appropriate comparison series for
k =
k² + 2k + 1
₁k³ + 5k +7
is Σ 1/1 10
k = 1k
