What equation has infinite many solutions? 1. 3(n+7)-6=2n+10+n
2. 3n-3=5(n+2)-2n
3. 2n+3(n-4)+5=5n-7
4. 2n-4=2n-2(n+2)

thank you :))

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.
