Select all the expressions that are equivalent to 16x - 2 - 24x + 4? 1) 4 + 16x - 12(1 + 2x) 2) 40x - 16 3) 16x - 24x - 4 + 12 4) -8x - 8

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.
