Subtracting a number is the same as adding its opposite.
Use this understanding to complete each of the equations below.

answer:

1) 7

=2

2) (-7)

=-13

Step-by-step explanation:

so simply the two negatives would cancel eachother out so it would be -5 + 7 which is just 7-5 = 2 which is the same thing as -5 + 7 so your answer is 7 with a final answer of 2

then for the next one it’s the opposite so it would be -5 + (-7)

which then = -13

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.
