What is the limit (if there is one) of the series of numbers? Start by making a table for each series and calculate the value of the series, as more terms are included in the series

1. 1-1/3+1/5-1/7+1/9

Number of terms added Sum of these terms

2. 1+ 1/1+1/(1*2)+1/(1*2*3) + 1/(4!)

3. 1+½+¼+1/8

4. 1+ 1/(2^2) + 1/(3^2) + 1/(4^2)

5. 2/1*2/3*4/3*4/5*6/5*6/7*8/7*8/9
