Write the rational number 0.3 in the form ab , where a and b are integers.

Step-by-step explanation:

Given

Required

Represent as

Let

This can be further written as

Multiply the numerator and denominator by 10

Since 3 and 10 are both integers, then

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.
