Find the cardinal number of each of the following sets. Assume the pattern continues in each part. a. {19, 20, 21, ..., 97} b. {4, 6, 8, 10,..., 1004} c. {xx=1, 2, 3, ..., 63} d. {xx=x+6 and XEN} a. The cardinal number of {19, 20, 21, 22, ..., 97} is b. The cardinal number of (4, 6, 8, 10, ..., 1004} is c. The cardinal number of {x21x = 1, 2, 3, ..., 63} is d. The cardinal number of {x|x=x+6 and XEN} is
