Lester gathers eggs from the hen house every morning. The eggs Lester gathers is given by the sequence 1, 5, 9, 13, … Which explicit equation represents this sequence? a) f(n) = 1 + 5( n− 1)

b) f(n) = 1 + 4( n− 1)

c) f(n) = 4 + 1( n− 1)

d)f (n) = 4 + 5( n− 1)

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

one set of data has more variation than the other. hope this !
