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
If x = 2 + y then by substitution . . .
8 (2 + y) - 2y = 22
16 + 8y - 2y = 22
6y = 22 - 16
6y = 6
y = 1
And x = 2 + y = 2 + 1 = 3
Therefore, in (x, y) format . . . (3, 1)

Answer:
I would say 135 would be the least three-digit number that is divisible by 3, 5, and 9.
Step-by-step explanation:
L x w = 150+175t
=> l = (150+175t)/25
l = [25(6+7t)/25]
l = 6+7t
The expression of the length is l=6+7t
