Jacob strode up 24 steps in 12 seconds to reach his apartment on the second
floor. How many steps did he climb in 9 seconds?

I think the answer is 3

Step-by-step explanation:

I know the 24 can go into 12 twice, and I know 3 can go into 9 three times. Don't know if this is the real way to solve it, but I do think this answer is correct. If not I am truly sorry. Let me know either way. :) Thanks!

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.
