5.11. A sequence is given by: 10,22, 50, 110, 1000, 40, 4, 0.4, 0.04, 0.004, ... a. Explain why this sequence is decreasing even though it initially seems to be increasing b. The definition on page 7 of the lecture notes says A sequence is said to be decreasing provided there is some positive integer N for which anan+1 for all n N We see that aN > AN+1 > AN+2 >... Identify the value of N for this sequence c. Explain what is a monotonic sequence?
