Answer:
I think it's 337 or 338
Step-by-step explanation:
you divide the number of 7th graders by the radio to 8th graders and multiply it by the radio of 8th graders to 7tg graders.
False
because
r=2
so
an=a1r^(n-1)
a4=(-1)(2^(4-1))
=(-1)(2^3)
=(-1)(8)
=-8
so a4 equals -8 not -6
This is what the graph looks like hope this helps:)
