The timings

An infinite series is a thing which to me is "always there". When we talk of measuring behavior for example. 

A finite series is a snap.  An expression which stays for a limited amount of time. I have made some finite expressions earlier.

Here is an equation below which has infinite and finite equivalence. I wish to state that infinite and finite equivalence exist. Permanance can be quantified to finite terms. 

2 to the power k is sigma of n from  0 to k of combination (k,n) is a finite form.

32 is 2 to the power 5. 128 is 2 to the power 7. And 256 is 2 to the power 8.

Here are the six expressions which is infinite to finite equivalence. 

What I mean is 

Also if the terms are reciprocated the infinite sum becomes 1/2^k.

Kindly check before accepting. 

Have a nice day !!
