Answer:
27
Step-by-step explanation:
green is 30%
blue is 50%
red is 6 marbles which when calculated is equal to 20%
blue would then be 15 marbles as the whole 100% would equal to 30 marbles
if 40% is added which is also 12 marbles then 15+12 = 27

Answer:
26,244
Step-by-step explanation:
The sequence is geometric with a common ratio of -3. The general term is ...
an = (a1)r^(n-1)
The first term is 4, so we have ...
an = 4·(-3)^(n-1)
For n=9, we find the 9th term to be ...
a9 = 4·(-3)^(9-1) = 4·3^8
a9 = 26,244
