Identify the following series as arithmetic, geometric, both, or neither.

3a + 3a² + 3a³ + . . + 3an

arithmetic
geometric
both
neither

Option 2 - Geometric series  

Step-by-step explanation:

Given : Series

To identify : The following series as arithmetic, geometric, both, or neither.

Solution :

According to the series,

If we take 3 common,

the above series make is a geometric series as 3 is a constant.

Geometric series is where ratio of two terms is

In the above given series, the common ratio is a.

As the series satisfy all conditions of geometric series.

Therefore, Option 2 is correct.

i would be 2,000 just get the square root of 50 which is 2500 and the divid 4/5 and last thing multiply the answer you get for that by the square root of 50
