Any geometric sequence can be expressed as:
a(n)=ar^(n-1), a=initial term, r=common ratio, n=term number
We are given that a(5)=1/16 and r=1/4 so we can say:
1/16=a(1/4)^(5-1)
1/16=a(1/4)^4
1/16=a/256
256/16=a
16=a
So the initial term is 16 so our formula is:
a(n)=16(1/4)^(n-1)

Answer:
Correlation Coefficient r value of 0.05 means a weak or very weak positive relationship while
Correlation Coefficient r value of 0.80 means a strong positive relationship
Step-by-step explanation:
Correlation Coefficient (r) signifies the strength of relationship which exists between two linear variables. The value of r ranges from - 1 to + 1 where positive and negative values signifies a positive and negative relationship relationship respectively.
The closer the r value is to either +1 or - 1, the greater the strength of the relationship while a r value of 0 means, there is no relationship between the two variables.
Hence in the scenario above :
Correlation Coefficient r value of 0.05 means a weak or very weak positive relationship while
Correlation Coefficient r value of 0.80 means a strong positive relationship
