Identify the sequence as arithmetic, geometric, both, or neither
1.7,9,11,13
This increases 2 at a time. What kind of sequence is that?
To determine whether the sequence is arithmetic, geometric, both, or neither, let's first analyze the differences between consecutive terms.
The difference between the second and first terms is 9 - 1.7 = 7.3.
The difference between the third and second terms is 11 - 9 = 2.
The difference between the fourth and third terms is 13 - 11 = 2.
Since the differences between consecutive terms are constant (both equal to 2), we can conclude that the sequence is arithmetic.
