Answer:
Finite geometric series
Step-by-step explanation:
A Finite Geometric Series is a sequence of numbers in which each term is equal to the product of its predecessor with a constant q, called the ratio of GS. Similar to what happens with the set of numbers (-1, 2, -4, 8, ...).
One of the operations involving this type of sequence is the calculation of the product of the terms of a GS when it is finite.
