# Lesson Worksheet: Monotone Convergence Theorem Mathematics

In this worksheet, we will practice using the monotone convergence theorem to test for convergence.

Q1:

Which of the following describes the least upper bound of a subset of numbers?

• Athe number so that if for all , then
• Bthe number so that if , then
• Cthe number so that if for all , then
• Dthe largest number amongst all
• Ethe smallest number amongst all

Q2:

Suppose is a subset of real numbers that has an upper bound .

Suppose that is a least upper bound of . Which of the following relations between and must be true?

• A
• B
• C
• D
• E

Suppose is a second least upper bound for . Which of the following relations between and must be true?

• A
• B
• C
• D

Q3:

Consider the sequence for .

Is ?

• ANo
• BYes

Is ?
