Question

Write in set builder formq = (16, 25, 34, 43 ,52 ,61,70)

Answer 1

Answer:

A={16, 25, 34, 43 ,52 ,61,70}

A= {x/x, x=n2-n1= 9, n€N, 16<x<70}

Answer 2

Answer:

Set builder form is

{X :  X = 16 + 9n and n = 0,1,2,3,4,5,6 }

Step-by-step explanation:

There are two types

1. Roster form       2.  Set builder form

• Roster form tells about the listed elements ( as given in question )
• Set builder form tells about the formula or relation of listed elements written in curly brackets.

Step 1

find relation between elements

16+(9×0) = 16

16+(9×1) = 25

16+(9×2) = 34

16+(9×3) = 43

16+(9×4) = 52

16+(9×5) = 61

16+(9×6) = 70

16+(9×n) = X

Step 2

write in set builder form

{ represents all the numbers : relation of all the numbers in the set }

{X :  X = 16 + 9n and n = 0,1,2,3,4,5,6 }
