What is a number in between 0.213 and 0.214?

Answer 1

There are an infinite number of them.

Here are a few:

0.213000000009

0.21300000008

0.2130000007

0.213000006

0.21300005

0.2130008

0.213009

0.21304

0.2137

0.2138

0.2139

0.2139000001

0.2139000002

0.2139000003

.

.

etc.

If you want the number that's exactly mid-waybetween 0.213 and 0.214,

then that's the number called the "average" of 0.213 and 0.214.

To find it:

-- Add 0.213 plus 0.214 .

-- Divide the sum by 2 .

-- If you don't get 0.2135, then go back to step-1, because you made a mistake.
