Answer:
The first option is the right answer $ 845.16
Step-by-step explanation:
1.089.26-120=969.26
969.26+325=1.294.26
1.294.26-425=869.26
869.26-24.10= 845.16

Answer:
2x-6
Step-by-step explanation:
have a nice day!! :))
Step-by-step explanation:
it is geometric
so we will use this equation:
a(n)=a1*(r)^(n-1)
and we have a(1)=75 , r=15/75=3/15=1/3
explicit formula: a(n)=75*(1/3)^(n-1)
hope this helps
When n = 1 first term = -6
n = 2 second term = 0
n = 3 third term = 6
n = 4 4th term = 12
so we have an Arithmetic sequence first term = -6 and common difference = 6
Sum 14 terms = (14/2)[2*-6 + (14-1)*6]
= 462 answer
