The sequence forms a Geometric sequence as the rule to obtain the value for the next term is by ratio
Term 1: 1000
Term 2: 200
Term 3: 40
From term 1 to term 2, there's a decrease by
From term 2 to term 3, there's a decrease also by
The rule to find the
term in a sequence is
, where
is the first term in the sequence and
is the ratio
So, the formula for the sequence in question is
term =
The sequence is a divergent one. We can always find the value of the next term by dividing the previous term by 5 and if we do that, the value of the next term will get closer to 'zero' but never actually equal to zero.
We can find a partial sum of the sequence using the formula
for -1<r<1
Substituting
and
we have
=
= 1250
Hence, the correct option is option number 1
if ∡PQR = 82°, and the ray QS bisects it, it cuts ∡PQR into two equal halves, ∡PQS and ∡RQS, each of which is then 82/2, or 41°.
She gets $2.75 back if that’s what you’re asking.

2 dollars for each book so you multiply it by the number of books and add 15 because it is a one time fee.
4+x <u><</u> 8: i believe this would be the right answer
