What is 4+5 this is for specile peson

4+5=9

Step-by-step explanation:

if you count and do the math you'll see that

1 2 3 4 (5)

and then

1 2 3 (4)

is the same as

1 2 3 4 (5) + 6 7 8 9

9

Step-by-step explanation:

answer: the dogs need to shift their focus to human scent.

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.
