Multiple Choice

1. What is the common difference in an arithmetic sequence?

• The result of adding all the terms

• A fixed value added to each term to get to the next term

• The largest number in the sequence

• The sum of the first and last terms

  
  

Multiple Choice

2. Define the term "arithmetic sequence."

• A sequence of random numbers

  
  

• A sequence with decreasing terms

  
  

• A sequence of numbers where each term is determined by adding a constant value to the previous term

• A sequence that includes only even numbers

Multiple Choice

3. How do you calculate the nth term (an) of an arithmetic sequence using the explicit

• a_n = a * n

• a_n = a + n

• a_n = a + (n - 1) * d

• an = n / d

Multiple Choice

4. Explain why arithmetic sequences are special.

• They contain only prime numbers

• They have a consistent common difference between consecutive terms

• They are always decreasing

• They have an infinite number of terms
