mathmath333 · Answer

how is it related to tetahadal ?

faiqraees · Answer

Multiply each tetrahedral number with 7

mathmath333 · Answer

bibobo how did u find that tetahadal connection?

bobo-i-bo · Answer

As FaiqRaees said, each is a multiple of 7 so I divided it by 7 then searched up the sequence 1,4,10,20... hence the cheating :P

mathmath333 · Answer

ok i got that , but how did u find that cuz when i google search the numbers i didnt find any tetahadal

bobo-i-bo · Answer

But on hindsight, noticing the sequence of the difference between the terms of the sequence 1,4,10,20... is 3,6,10... should be enough to notice that that sequence is the sequence of triangular numbers

faiqraees · Answer

search 1,4,10,20
