Will mark brainiest! The first question since it got cut off is : (A) is the sequence arithmetic, geometric, or neither? How do you know?

Geometric, 81, 3

Step-by-step explanation:

A geometric sequence is defined as one that continues with multiplication.

We can tell that the sequence proceeds by multiplying 1/3.

a2 is 81 because it is the second term given in the sequence.

a5 is 3 because it equals a4 *1/3, which is 9*1/3 which is 3

I hope this helps! :)

i got 10.28 but that rounds up to 10.3
