Determine whether each sequence is arithmetic of geometric. Find the next three terms.
C. Arithmetic, 34,39,44
D. This sequence is neither arithmetic or geometric.
Is the answer C?
In an Arithmetic Sequence the difference between one term and the next is a constant.
19 - 14 = 5
24 - 19 = 5
29 - 24 = 5
So difference = 5
29 + 5 = 34
34 + 5 = 39
39 + 5 = 44
But a geometric sequence is when you times it and arithmetic is when you add it. So the answer has to be C, because C answer and A's answer are the same except arithmetic is the right answer.
The answer is C. The common difference between all the terms and the theorized next three terms is 5.
