Questions and Answers
If the first term of an arithmetic sequence is 3 and the common difference is 5, what is the fifth term of the sequence? Consider that each term can be found by adding the common difference to the preceding term.
In the arithmetic sequence where the first term is 10 and the common difference is -2, what will the seventh term be? Understand that a negative common difference will decrease the terms as you progress in the sequence.
An arithmetic sequence has its first term as 4 and its fifth term as 20. What is the common difference? This situation requires you to identify how the position of the term relates to both the first term and the common difference.
If an arithmetic sequence starts with a term of -8 and has a common difference of 7, what will be the third term? Recognize that each term can be calculated sequentially by adding the common difference to the prior term.
