The 7th grade students at palm coast middle school made some apple pies for a bake sale. the school cafeteria also donated 9 pies toward the effort. all the pies at the sale were cut into 8 pieces. if at least 224 pieces of pie were sold in all, how many pies did the students bake?

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.
