Answer: C
Step-by-step explanation:
The starting amount (a1) = 4
The rate is -3 because 4 * -3 = 12 and -12 and -12 * -3 = 36 etc.
Answer: C.
The first number is a positive 4, which is your a1. Then the geometric sequence goes to a negative implying that it is multiplied by a negative. So the a1 = 4 and it is being multiplied by a negative 3.
Answer:
like look at you
H:182000
L=28000
Step By Step
H=House
L=Lot
H+L=210000
H(6.5)=L
L+(L(6.5)=210000
28000(6.5)=H
x = 4
all angles in triangle add to 180
90+70=160
180-160=20
20÷5=4
i think the answer is a
x < 1 or x > 6
