ribbon. She decides the width of the board should be
of the length.
If she has 100 inches of ribbon, what is the largest
board with whole number dimensions that she should
cut?

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.

answer:      

step-by-step explanation:

a - base

b - exponent

so,
