What indicates that a sequence cannot be arithmetic?

• If it is multiplied by the same amount each time

• If it increases by the same amount each time

• If it decreases by the same amount each time

• If it changes by a different amount each time

What is the first step in identifying the pattern of a number sequence?

(a)  

• Finding the common ratio

• Calculating the sum of all terms

• Determining if it's a geometric sequence
