# AP GP & HP

I can understand AP, that it is a sequence in which difference of any two consecutive no.s is same but I cant understand what are GP & HP. Can anyone tell me somewhat briefly.

In a GP, the ratio of any 2 consecutive terms is same. This means that when you divide any term by the term preceding it, you get a constant ratio. If you take the reciprocal of all the terms of an AP in order, it forms an HP. Hope it helps. · 3 years, 1 month ago

Do you know about AP-GP-HP inequalities? · 3 years, 1 month ago

Yes, I do, but I know only the inequality AM>=GM>=HM. I'm callow in its various applications. · 3 years, 1 month ago

So Am I. :( I can't fathom of improving in such deep rooted concepts. Know any such method? Are you good at geometry? · 3 years, 1 month ago

I do not intend to sound absurd, but you've used the word 'fathom' at the wrong place. Fathom can literally be swapped with 'understand' most of the times. And of your second question, I'm average in geometry, but I suck at trigonometry. · 3 years, 1 month ago

Ah! You can perhaps make a living out of your english knowledge and the expertise in using complex jargon. Correct me again, if you find a syntax mistake :P · 3 years, 1 month ago

How can it be I who uses complex jargon? 'Jargon' is the specialized vocab in certain specific fields, like 'medical jargon'. And I'm sure I don't restrict my language to a specific, recondite subject. · 3 years, 1 month ago

Why don't you follow people at all??? · 3 years, 1 month ago

Earlier I used to follow loads of people, but then my home page seemed to be replete with unimportant discussions and notes, and good questions got buried deep under them. I was so fed up that I un-followed everybody, but believe me, I see their posts regularly. · 3 years, 1 month ago
