Because it was being impeached
Answer:
I believe it is D
Step-by-step explanation:
Hope this helps!
A1 = first term
a1 = 15
---------------------------------------------
d = common difference
d = (second term) - (first term)
d = a2 - a1
d = 9-12
d = -3
The negative common difference indicates that the terms are decreasing
Each time we subtract 3, or add -3, to get the next term.
----------------------------------------------
nth term of arithmetic sequence
an = a1 + d(n-1)
an = 15 + (-3)(n-1)
an = 15- 3n + 3
an = 18 - 3n
Answer is choice D
6^3x+2=216
The steps on solving this problem is first write MDAS which means mutliplication is first so first you multiply 6^3x+2 after your done you get 18^x+2=216
and thats how you do it. (I hope that help cause I showed my teacher this question she kinda helped me with it..)
