Choose the correct description of the set a= {5, 10, 15, 20…}

a={x│x is a multiple of a natural number and -5}

a={x│x is an odd integer}

a={x│x € n and x is a multiple of 5}

option C

Step-by-step explanation:

set A= {5, 10, 15, 20…}

5, 10, 15, 20…  are the multiples of 5

Here all the numbers are positive and all the numbers are rounded numbers

5, 10, 15, 20… are the natural numbers and they are represented by N

So set A is x such that x is a natural number and x is a multiples of 5

Its option C
