The above series is a Geometric series because:
t2/t1 = t3/t2 --> 14/7 = 28/14 --> 2 = 2
and common ratio (r)=2
The for S12 we have,
S12 = a(1 - r^12) /(1-r) where, a = first term = 7
or, s12 = 7*(1 - 2^12) / (1 - 2)
= 28665
I don't think I know how to completely help you with this question, but I can help get you started. Basically, A=432 W=3/4L L=X (because that's the variable that you're trying to find.) So, overall the setup would be: 3/4X=432
I hope this helps cx
Answer:
500+6
Step-by-step explanation:
You multuply what is in the parentheses, so you do 5×100 then you do 6×1
