Question

Express the set of natural numbers less than in roster form

a) {0, 1, 2, 3, ...}
b) {1, 2, 3, 4, ...}
c) {0, 1, 2, 3, 4, ...}
d) {1, 2, 3, ...}

Answer 1

The set of natural numbers less than 'n' can be expressed in roster form as {0, 1, 2, 3, ..., n-1} or {1, 2, 3, 4, ..., n}.

Step-by-step explanation:

The set of natural numbers less than n can be expressed in roster form as:

a) {0, 1, 2, 3, ..., n-1}

b) {1, 2, 3, 4, ..., n}

c) {0, 1, 2, 3, 4, ..., n-1}

d) {1, 2, 3, ..., n}

For example, if n is 10, then the set of natural numbers less than 10 in roster form would be:

a) {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

b) {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

c) {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

d) {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
