 Hello, For a math assignment I am evaluating different values for pi and plotting them into a table. One formula that I have to use is the Ramanujan-Sato series. For some reason, when I set it to calculate it puts the same value in the table 'i' amount of times. Tab3 = Table[1/N[(2*(Sqrt/99^2))* Sum[((4*i)!/i!^4)*((26390*i + 1103)/396^(4*i)), {i, 0, k}]], {k, 100}] I have to add the value for each summation step into a table and then plot that table. I don't understand why this isn't working and neither does my supervisor, any help would be greatly appreciated. Answer

 The value 100 for k is rather high! And you should take into account, that every iteration adds about 8 correct digits: Column[Table[ 1/N[(2*(Sqrt/99^2))* Sum[((4*i)!/i!^4)*((26390*i + 1103)/396^(4*i)), {i, 0, k}], 9 + k 8], {k, 8}]]  Answer
