Question 1 • EA Pre-Calculus Credit Recovery

Which of the following describes the sequence 1, 1, 2, 3, 5, …

Answer
A
arithmetic
B
geometric
C
neither
D
both

Explanation

An arithmetic sequence has a constant difference between consecutive terms. Here the differences are 0, 1, 1, and 2, so they are not constant. A geometric sequence has a constant ratio between consecutive terms, and the ratios here are not constant either. Therefore, the sequence is neither arithmetic nor geometric.
