The following video gives some 'proof' to the formula for infinite geometric series... Try not to over-complicate this topic. TRUST ME, it will get over-complicated when you get to calculus. For now, go with the plan. :-)

Move each sequence to the appropriate type: Arithmetic or Geometric

  • 13.5, 13.75, 14, 14.25, ...
  • 63, 15.75, 3.9375, 0.984375, ...
  • 90, 45, 22.5, 11.25, ...
  • 125, 195, 265, 335,...
  • Arithmetic Sequence
  • Geometric Sequence

Find the sum of the infinite geometric series, if it exists.
(just type the answer...if it doesn't exist type 'does not exist')

NOTE: Be sure to use the fraction in your equation..desmos is going to give you a rounded decimal on the x-axis...find the r and use the fraction NOT the decimal or your answer will be off.
