Plz ! 25 points for brainliest !
an arrangement of billiard balls has 5 balls in the first row and 16 rows in all. in each successive row one ball is added.
what is the explicit rule for this situation, and how many balls will be in the 16th row?
drag and drop the answers into the boxes to match the situation.
picture is
edit: for you poor souls in the future trying desperately to find the answer, as am i, here you go:
explicit rule: an=5 + n
number of balls in the 16th row: 20
good luck my fellow gamers.

maybe i can

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
