The number of terms意思

"The number of terms" refers to the total number of elements or members in a set or sequence, such as a list, series, or sum. In mathematics, a term is an individual element in a set of numbers, letters, or other mathematical expressions that are separated by a plus sign (+) or a minus sign (-).

For example, in the arithmetic series 2 + 4 + 6 + 8 + ..., the number of terms would be the total number of numbers that are added together. If the series is infinite, the number of terms is infinite. If the series is finite, like 2 + 4 + 6 + 8 + 10, the number of terms is 5, as there are five different numbers being added.
