How can you find the sum of an arithmetic series when you’re given only the first few terms and the last one? There are two formulas, and I show you how to do it. You need to find “n” for the last term.

MIT grad shows how to find any limit as x approaches a finite value/constant value (and not infinity). To skip ahead: 1) For an example of PLUGGING IN/SUBSTITUTION, skip to time 1:45. 2) For FACTORING to simplify, skip to 3:53. 3) For GETTING A COMMON DENOMINATOR, skip to time 8:09. 4) For EXPANDING by opening […]
