Calculate terms in a Series
Hi can someone tell me how to set this up? Thank you.
Calculate the next 3 terms in the series 1/4 +1/9+1/14+1/19+... -- Barbara |
Not sure what you want to show in the cells, but assuming the 1st term, 1/4 is
in A1, and you want 1/9 in A2, 1/14 in A3, etc, in A2 put this formula and copy it down. =1/(1/A1+5). You can format with a Fraction format to show as 1/4, 1/9, 1/14, etc. On Sun, 2 Oct 2005 19:09:01 -0700, "BarbV" .(donotspam) wrote: Hi can someone tell me how to set this up? Thank you.

Another formula that will work and doesn't require putting 1/4 in the top cell
is the following, in row 1 of any column: =1/(ROW()*5-1) On Sun, 02 Oct 2005 22:01:24 -0500, Myrna Larson wrote: Not sure what you want to show in the cells, but assuming the 1st term, 1/4 is in A1, and you want 1/9 in A2, 1/14 in A3, etc, in A2 put this formula and copy it down. =1/(1/A1+5).

If you question is how to do a summation in Excel, Myrna has given you
an answer. If instead you are wanting help identifying the particular sequence that you are summing, http://www.research.att.com/~njas/sequences/ is the standard tool. There are a number of possibilities for the next term in 4,9,14,19, depending on the mechanism for generating the first four terms. Jerry BarbV wrote: Hi can someone tell me how to set this up?

Thank you for your help.
