Answer:
No it is not.
Step-by-step explanation:
Reason.
For geometric: common ratio r should be equal
r = T2/T1 = T3/T2 but is not true here as -6/-14 is not equal to 2/-6
Answer:
19/50
Step-by-step explanation:
Let d represent number of days and n represent number of workers.
We have been given that when building a house, the number of days required to build varies inversely with with the number of workers.
We know that the equation
represents the relation where y is inversely proportional to x and k is the constant of proportionality.
So our required equation would be 
Upon substituting our given values, we will get:



Since constant of proportionality is 665, so our equation would be
.
To find the number of days it will take to build a similar house with 5 workers, we will substitute
in our equation as:


Therefore, it will take 133 days for 5 workers to build a similar house.
