The sum of the product of 8 and 2 and the difference of 16 and 4

Step-by-step explanation:

The sum of the product of 8 and 2 and the difference of 16 and 9.

This is like saying adding (8 multiplied by 2) and (16 subtracted by 9)

This means the expression is

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.
