Frequently Asked Questions (FAQ)
How do you calculate an arithmetic sequence?
The formula for the nth term of an arithmetic sequence is a_n = a_1 + (n-1)d, where a_1 is the first term of the sequence, a_n is the nth term of the sequence, and d is the common difference.
What is an arithmetic Sequence?
An arithmetic sequence is a sequence of numbers in which each term is obtained by adding a fixed number to the previous term. It is represented by the formula a_n = a_1 + (n-1)d, where a_1 is the first term of the sequence, a_n is the nth term of the sequence, and d is the common difference, which is obtained by subtracting the previous term from the current term.
How do you know if a sequence is arithmetic or geometric?
An arithmetic sequence has a constant difference between consecutive terms, while a geometric sequence has a constant ratio between consecutive terms.
