Chapter 5: Progression

What is arithmetic progression?

• A sequence of number obtained by adding a constant to the term before it.

• A sequence of number obtained by add 3 to the term before it.

• A sequence of number obtained by multiply a constant to the term before it.

• A sequence of number obtained by times 4 to the term before it.

What is geometric progression?

• A sequence of number obtained by adding a constant to the term before it.

• A sequence of number obtained by add 4 to the term before it.

• A sequence of number obtained by multiply a constant to the term before it.

• A sequence of number obtained by times 5 to the term before it.

What is the common difference?

• A constant that is added to previous term to form an arithmetic progression.

• A constant that is multiply to previous term to form a geometric sequence.
