Sometimes, we want to find the sum of the first however many terms of a geometric sequence. If there aren't many terms to count, this is nice and easy. However, if you want to quickly add the first 50 terms, for example, adding them manually would take a long time. We want a sho...

The fact that a geometric sequence has a common factor allows you to do two things. The first is to calculate any random element in the sequence (which mathematicians like to call the "nth" element), and the second is to find the sum of the geometric sequence up to the n...

Therefore, the minimum sum of our infinite geometric sequence is (E)4. (Solution by akaashp11) As an extension to find the maximum value for the denominator we can find the derivative of −r2+r to get 1−2r. we know that this changes sign when r=12 so plugging it in into the ...
