Python cannot find the name "calculate_nt_term" in the program because of the misspelling. Below you can see the first 10 numbers in the sequence: Thats pretty much everything we need to know to create a Python program that generates this sequence. This makes our code easier to read (imagine if the calculate_nth_term function was 50 lines long): We have defined the function we are calling so why the error?if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[250,250],'codefather_tech-large-mobile-banner-2','ezslot_10',139,'0','0'])};__ez_fad_position('div-gpt-ad-codefather_tech-large-mobile-banner-2-0'); Because we are calling the function calculate_nth_term before defining that same function.

A name can be either related to a built-in function or to something you define in your program (e.g. --> 364 x = Flatten(name='flatten')(x) It works the same in Python 3.
