Find the cardinal number for the following sets

A = {114, 115, 116, 117, ...173}

B = {114, 116, 118, ... 414} 

 

Set A = { 114, 115, 116, 117, ...173 }
subtract from each element 113 we have 1, 2, 3, ... , 60
n(A) = 173-113 = 60

 

Set B = { 114, 116, 118, ... 414 }
subtract from each element 112 we have 2, 4, 6, ... , 302
302 = 2n

so

n(B) = 302/2 = 151
