Which process helps determine the average of the first and last elements in an evenly spaced set?

Finding the median

Calculating the range

Computing the mode

Evaluating the mean

The process that helps determine the average of the first and last elements in an evenly spaced set is evaluating the mean. When dealing with an evenly spaced set of numbers, the mean, or average, can be found by taking the sum of the first and last terms and dividing by two. In this context, since the set is evenly spaced, the mean essentially represents the middle value, which is also the average of the first and last elements.

In an evenly spaced set, the distance between each successive number is consistent, making the mean a reliable measure of central tendency. This approach simplifies finding the average because, due to the uniformity of the spacing, the mean will always lie exactly in the center of the first and last number. Understanding this principle is key when analyzing arithmetic sequences or any evenly spaced quantitative data.
