Question

Write with reason, whether the following set is finite or infinite.

A = {x | x < 10, x is a natural number}

Answer 1

A = {x | x < 10, x is a natural number}

A = {1, 2, 3, 4, 5, 6, 7, 8, 9}

So, A is a finite set.

Reason: Natural numbers are counting numbers that start from \(1\) and increase by whole numbers (1, 2, 3, ...).
