Which of the following best describes the set of numbers? -1, 2, -4, 8,
-infinite arithmetic series
-finite geometric series
-infinite geometric series
-infinite alternating sequence

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.

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
