Question

c=(x:x=2n,n € N and n<=5)​

Answer 1

c={2,4,6,8,10 }

hope it helps..

Answer 2

Solution:

Given

C = {x:x=2n, n€N and n≤5}

Now ,

n = 1,2,3,4,5

i ) if n = 1 then x = 2×1 = 2

ii) if n=2 then x = 2×2 = 4

iii) if n=3 then x = 3×2 = 6

iv) if n=4 then x = 4×2 = 8

v) if n=5 then x = 5×2 = 10

Therefore,

Roster form of C is

C = { 2,4,,6,8,10 }
