Answer:

let common difference be d.

a 18=a+17 d

a 14=a+13 d

a+17d - (a+13d) =32

a+17d - a - 13d =32

17d - 13d = 32

4d = 32

d=32/4

d=8

common difference=8

Answer:

Mochi

Step-by-step explanation:

Mochi

Each week theres a increase of 4 in Mochi's weight. So you will add 4 twice to get to the 5th week.

4th week : 17

5th week : 21

Kappa

In 4 weeks Kappa weighed 14, which is less that Mochi at the pace Kappa is going at.

on the 3rd week Kappa weighed 11

and 2nd week Kappa weighed 5

and 1st week Kappa weighed 3

Looking at the graph, we can give a rough estimate on the 5th week it's going to be 16 or 17 either way making Mochi heavier.

ahrayia [7]

Answer:

There are 49 corrupt senators and 1 honest senator.

Step-by-step explanation:

Freedonia has 50 senators. Each senator is either honest or corrupt. At least one of the Freedonian senators is honest.

As we can see that there are no two senators where both of them are honest. So either there is one senerator who is honest or none.

As given that at least one of the Freedonian senators is honest.

Hence, we can conclude there is one and only one honest senator.
