What is non terminating and repeating decimal?

Answer 1

A non-terminating decimal is a decimal that does not terminate, and goes on forever, and a repeating decimal is a number that continues on forever with a repeated pattern

Answer 2

Non terminating means that when represented as a decimal, the digits go on forever. In this class there are two types: There are repeating, such as 0.333333... which equals 1/3 and 0.090909.... which equals 1/11. Then there are non-repeating, which go on forever without a repeating pattern. These are the irrational numbers, such as pi, e, and square root of 2.
