Define Rational Numbers?

in arithmetic, a number that can be represented as the quotient p/q of two integers such that q ≠ 0. ... In decimal form, rational numbers are either terminating or repeating decimals. For example, 1/7 ,0/1, 77/9

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.
