PLEASE HELP!! What are the explicit equation and domain for a geometric sequence with the first term of 3 a second term of -9?
2 answers:
Answer:
The correct answer is c.
Answer:
the third option
Step-by-step explanation:
a1 = 3
a2 = -9
as a geometric sequence every sequence item is created by multiplying a constant factor with the previous item.
what do I need to multiply 3 with to get -9 ? right, -3.
so, the first 2 options are out, because they multiply with -12.
and we can accept only n>=1, because there is no a0. it starts with a1.
ah only the third option is right.

Answer:
Your answer would be 2
Step-by-step explanation:
15 - 6(x+1) =12
15- 6*x +6*1 = 12
15 - 6x + 6 = 12
15 - 6 + 6x = 12
9 + 6x = 12
9 - 9 + 6x = 12 - 9
6x = 3
x = 2
