Fatima and rihana are playing battleship. they labeled their axes using just whole numbers.
a. fatima’s first guess is (2, 2). rihana says, "hit! " give the coordinates of four points that fatima might guess next.
b. rihana says, "hit! " for the points directly above and below (2, 2). what are the coordinates that fatima guessed?

1. (2,3), (1,2), (3,2), (2,1)

2. (2,4), (2,3), (2,1), (2,0)

Step-by-step explanation:

1. For the points near (2,2) we might just add a unit to move to the right or subtract one unit to move left. That would be the points (3,2) and (1,2).

Similarly to move up and down, we add/subtract one unit to the second coordinate, giving result to (2,3) and (2,1).

2. To move above and below the point (2,2) we add/subtract the units we want to the serving coordinate.

+2= (2,4)

,-2=(2,0)

+1=(2,3)

-1=(2,1)

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
