Question

write the roaster form of
C={x:x=n^2-1 n belongs to Natural number n<orEqual to 5}
​

Answer 1

Answer:

{0, 3, 8, 15, 24}

Step-by-step explanation:

n ≤ 5 (where n is natural numbers)

n = 1, 2, 3, 4, 5

x = n² - 1

n= 1

x = 1² - 1 = 1 - 1 = 0

n = 2

x = 2² - 1 = 4 - 1 = 3

n = 3

x = 3² - 1 = 9 - 1 = 8

n = 4

x = 4² - 1 = 16 - 1 = 15

n = 5

x = 5² - 1 = 25 - 1 = 24

therefore the set C

= {0, 3, 8, 15, 24}

hope you get your answer
