What is the Pattern in this Sequence?

  • Start date Start date
AI Thread Summary
The sequence presented starts as a clear arithmetic progression but then diverges unexpectedly. Participants discuss the next number, with many agreeing that 115 is the most logical answer. The reasoning involves adding 7 to the previous number, interpreted in octal representation. Some express surprise at the simplicity of the solution. The conversation highlights the blend of arithmetic and number representation in deciphering the pattern.

What is the next number?.

7, 16, 25, 34, 43, 52, 61, 70, 77, 106...?

Wow, that makes no sense. It starts of as a nice, clean arithmetic sequence. And at the end it goes on doing strange things...

I guess I need to think some more about it...


Does the next number end with a 5?

Bah. Saw it right away.

There are a few possible answers, but best answer is 115.
 
Ah, I get it now :smile:

Is it 115?
 
I think I get it. Is it adding 7 to the number in octal representation, so that the next number would be 115?

Yep. Sorry if it was too easy! =P
 

Thread 'Non-orthogonal bases'

Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
