Question

How is {x:x is an integer and x<4} an Infinite set because it is mentioned x<4?​

Answer 1

Answer:

Integers are represented by { . . .-4, -3, -2, -1,  0,  1,  2,  3,  4, . . .}

It includes all negative numbers as well.

The (. . .) shows that there are infinite numbers on either side.

So {x: x is an integer and x < 4} = { . . .-3, -2, -1,  0,  1, 2, 3}

∴ It is an infinite set.
