an example of an nonterminating decimal

Answer 1

0.333333333
or, with a pattern, but nonrepeating, 0.30300300030000...
or, with no pattern, √2 = 1.41421356...

Answer 2

sorry: 0.3333333333...

Answer 3

I will assume you meant non-repeating and non terminating decimals.

π or e
or 4.56566566656666...
or 10.1234567891011121314.. can you see what I am doing here ?
√41, log(54), ....

just non-terminating decimal would be something like 4.3333....
12.343434...
or any of the others I mentioned
