Determine whether the given number is an irrational number or a rational number and place it in its representing category
v120
Irrational Numbers
Rational Numbers
V36
7
10
148
781

See below

Step-by-step explanation:

√120 is irrational since it cannot be written as a fraction

√36 is rational because it can be written as 6 or -6 which are both rational

7 is rational because it can be written as a fraction (ex. 7/1, 14/2, 21/3, etc.)

10 is rational because it can be written as a fraction (ex. 10/1, 20/2, 30/3, etc.)

148 is rational because it can be written as a fraction (ex. 148/1, 296/2, 444/3, etc.)

781 is rational because it can be written as a fraction (ex. 781/1, 1562/2, 2343/3, etc.)

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.
