Use set builder notation to describe these sets.

a) s1 = {1, 2, 4, 8, }
b) s2 = {2, 5, 8, 11, }
c) s3 = {1, 4, 9, 16, }
d) s4 = {a, b,c, d,e, f z}
e) s5 = {a, e,i, o,u}

a) S1 = { 2^x | x belongs to the set of Whole Numbers}

b) S2 = { 2+3(x-1) | x belongs to Natural Numbers }

c) S3 = { x^2 | x belongs to the set of Natural Numbers  }

d) S4 = { x | x belongs to English Alphabet }

e) S5 = { x | x is a Vowel of English Alphabet}

Explanation:

Whole Numbers = {0, 1, 2, 3, ...}

Natural Numbers = {1, 2, 3, ...}

English Alphabet={a, b, c, d, e, ... , x, y, z }

Vowels of English Alphabet = {a, e, i, o, u}
