EnglishDefinition
a sequence of numbers a1, a2, a3,… such that their reciprocals 1/a1, 1/a2, 1/a3,… form an arithmetic sequence (numbers separated by a common difference).
Examples
- 1.Unfortunately, the test series on the right is a harmonic series which is known to diverge (p-test), which is exactly the situation when comparison fails.
