here i am trying to catch up on these blogs lol

Infinite Sums
Notes
• You can only find the infinite sum of a geometric series, it will not work for an arithmetic series
• You can only find the infinite sum of a geometric series if r < 1
• The formula for finding the infinite sum of a geometric series is as follows:S= ((t1) / (1-r))
• To find where an infinite geometric converges, set r < 1 and solve for x
• how to write a repeating decimal as a fraction. To do this follow this formula: (whats repeating / place-1)

Example

Find the sum of the infinite geometric series.
6 + 12 + 24…
r= 12/6= 2 24/12=2

solve
6/1-2=6/-1= -6

YAY!! i did a blog
