The given sequence is neither arithmetic nor geometric.
Further explanation:
In order to check whether a sequence is geometric or arithmetic we have to find the common ratio and common difference respectively
Common difference is the deifference between cunsecutive terms of a sequence while common ratio is the ratio between two consecutive terms.
Common difference is denoted by d and common ratio is denoted by r
- If the common difference is same then the given sequence is an arithmetic sequence
- If the common ratio is same then the given sequence is a geometric sequence
Given
1, 3, 6, 10, 15
Common difference:
Here

As the common difference is not same, the given sequence is not an arithmetic sequence
Common Ratio:

As the common ratio is also not same the sequence is not a geometric sequence.
The given sequence is neither arithmetic nor geometric.

The rate of change is equal to the slope of a line. Given any 2 points on a line and you can calculate the slope (rate of change) of that line. The formula for rate of change is given by Δy/Δx which equals (y2-y1)/(x2-x1). Therefore, using the points given in the question and simply input them into our formula, we get ((4)-(3))/((-2)-(0)) = -1/2
