By applying basic property of Geometric progression we can say that sum of 15 terms of a sequence whose first three terms are 5, -10 and 2 is
<h3>What is
sequence ?</h3>
Sequence is collection of numbers with some pattern .
Given sequence

We can see that

and

Hence we can say that given sequence is Geometric progression whose first term is 5 and common ratio is -2
Now
term of this Geometric progression can be written as

So summation of 15 terms can be written as

Answer:
I'm pretty sure it's the 8 feet deep hole
Step-by-step explanation:
You're earning 8 dollars so that can't be negative.
Temperature can be negative but it doesn't have the - in front of it.
It would be a confusing question if that's the answer because then you'd be basically guessing at it.
I don't think it's the throw because you can't actually throw in negative/throw backwards for it to be negative.
8 feet hole is the only one that makes sense, since you're going down
I believe it is positive so option 2
