Webpartial sum. The sequence of partial sums is {Sn}. Definition An infinite series ∑∞ n= 1 an converges to a sum S if and only if the sequence of its partial sums {Sn} converges to S. Otherwise it diverges. I., ∑ ∞ n= 1 an = S ⇔ lim n→∞ Sn = S Example Find an expression for the n th partial sum of ∑∞ n= 1 1. Example Find the sum ... WebThe sum of the infinite terms of the geometric series is given by: [math]50=\dfrac {a} {1-r} [/math] Thus a=50* (1-r) (Call this equation 1) [math]a^2+a^2*r^2+a^2*r^4+...=150 …
