Fraction = 19/500
You can't write it as a mixed number
Mixed numbers have to have whole numbers.
19/500 is less than 1, therefore it cannot be a mixed number.
4 times 3=12
12 times 3=36
I think you want us to find the sum of the geometric sequence to n=15
the sum is
a1=first term=4
n=15
r=common ratio=3
S=-2(-14348906)
S=28697812
it adds to 28697812
Answer:
The Second Method
Step-by-step explanation:
APE (Absolute Percentage Error) = absolute difference / actual * 100
APE for First method = 61.93
APE for second method = 54.97
MAPE (Mean absolute Percentage error) = Sum of absolute Percentage error/ Number of observations. ( i.e., 4)
Then,
MAPE for the first method = 61.93 / 4 = 15.482
MAPE for the second method = 54.97 / 4 = 13.472
So, MAPE for second method is less than the MAPE for first method.
