Answer:
Option C) is correct
That is the given arithmetic sequence represents the recursive formula is f(n)=f(n-1)+(-5)
Step-by-step explanation:
The given arithmetic sequence is
Let f(1)=94,f(2)=89,f(3)=84,...
To find the common difference d :
,
Therefore d=-5
,
Therefore d=-5
Therefore the common difference d=-5
check the recursive formula which represents the given arithmetic sequence
Put n=2 and d=-5 in we get
Therefore f(2)=89
Put n=3 and d=-5 in we get
Therefore f(3)=84
and so on
Therefore the recursive formula where d=-5
Therefore the recursive formula represents the given arithmetic sequence

Answer:
The answer is w^2 + 2xw + x^2
84
Step-by-step explanation:
You turn 3 1/2 into a decimal which is 3.5. Then, you multiply the 3.5 by the 24 boards to get how many ft long all the boards together will be.
