Finding Common Differences in Sequences

Teacher MJ introduces arithmetic sequences, focusing on finding missing terms by calculating the common difference. The video provides step-by-step examples, demonstrating how to solve problems with given and missing terms. Students are encouraged to practice additional problems and engage with future content on non-consecutive terms.

What is the main topic discussed in the video?

• Solving quadratic equations

• Understanding geometric shapes

• Finding missing terms in arithmetic sequences

• Finding the common ratio in geometric sequences

How do you find the common difference when two consecutive terms are given?

• Multiply the two terms

• Divide the first term by the second term

• Add the two terms

• Subtract the first term from the second term

What should you do if you don't have two consecutive terms?

• Add the given term to its previous term

• Subtract the given term from its previous term

• Use the average of the terms

• Multiply the given term by its previous term

In Example 1, what is the common difference?

• 5

• 7

• 9

• 11

In Example 1, what is the next term after 39?

• 48
