Answer:
8th term of geometric sequence is 312500
Step-by-step explanation:
Given :
and common ratio (r) = 5
We have to find the 8th term of the geometric sequence whose
and common ratio (r) = 5
Geometric sequence is a sequence of numbers in which next term is found by multiplying by a constant called the common ratio (r).
......(1)
where
is nth term and a is first term.
For given sequence
a can be find using
and r = 5
Substitute in (1) , we get,
Thus, 8th term of the sequence denoted as 
Substitute n= 8 in (1) , we get,

Thus 8th term of geometric sequence is 312500
Answer:
6.569
Step-by-step explanation:
Difference is subtraction.
10.22-3.651=6.569
100-21=79
2859(0.79)^3=1409.598
worth $1409.60
Answer is B: 150
write two equations
r+s=190
4r+3s=720
solve by substitution
the get r=150 s=40
