How do you find #a_1# for the geometric series with #r=3# and #s_6=364#?

Answer 1

Can be done quite easily using the standard definition of a Geometric Series.

If the first term of the series is some #a#, then the equation we have is,
#a\times r^5=364# #a\times 243=364# (substitute #r=3#) #a=\frac{364}{243}#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
