Answer: Is there some answer choices? Because I can't help if I don't have any choices.
Step-by-step explanation:
Answer:B
Step-by-step explanation:
To find if a series is either geometric or arithmetic:
it must satisfy this property:
Arithmetic:
a(n+1) - a(n) = const
Geometric:
a(n+1)/a(n) = const
In your case:
r1 = 7 -4 = 3
r2 = 12 - 7 = 5
r1 != r2 (not arirthmetic)
Geometric check:
r1 = 7/4
r2 = 12/7
r1 != r2 (not Geometric)
so neither.
6 1/12 am I right? I'm pretty sure I'm right
