Arithmetic Sequences and Common Differences

The video tutorial explains arithmetic sequences, focusing on how each term is derived by adding or subtracting a constant value. It uses examples to demonstrate how to find subsequent terms in a sequence, emphasizing the consistent difference between terms. The tutorial provides a step-by-step approach to understanding and calculating terms in arithmetic sequences.

What is the common difference in the sequence starting from 8 and going to -14?

• -4

• 6

• -6

• 4

If the sequence starts at 8 and decreases by 6 each time, what is the fifth term?

• -26

• -20

• -14

• -32

In the sequence starting from 2, what operation is performed to get to the next term?

• Add 3

• Divide by 3

• Subtract 3

• Multiply by 3

What is the sixth term in the sequence that starts at 2 and decreases by 3 each time?

• -4

• -10

• -13

• -7

How do you determine the next term in an arithmetic sequence?

• Subtract the common difference from the last term

• Multiply the last term by the common difference

• Add the common difference to the last term

• Divide the last term by the common difference
