Mathematical Sequences and Series Quiz

What is a sequence?

• A random set of numbers

• A collection of unrelated terms

• A series of equations

• A set of numbers arranged in a definite pattern

What does the range of a function refer to?

• The set of all possible inputs

• The minimum value of the function

• The set of all possible outputs where x-coordinates do not repeat

• The maximum value of the function

What defines the Fibonacci sequence?

• A linear equation

• An arithmetic sequence

• A recursive formula

What are arithmetic means?

• The sum of all terms in a series

• The difference between consecutive terms

• Terms between two nonconsecutive terms of an arithmetic sequence

• The average of all terms in a sequence

What is an arithmetic series?

• The average of the first n terms

• The difference of the first n terms

• The product of the first n terms

• The sum of the first n terms

What characterizes a geometric sequence?

• The terms are all prime numbers

• The sum of terms is constant

• The quotient or ratio of any two consecutive terms is constant
