show that the series converges and find its sum using the ra
show that the series converges and find its sum using the ratio test. the sum k=0 to infinity ((1/2^k)-(1/2^(k+1))
Solution
Tn+1/Tn = (1/2)n+1 / (1/2)n
: 1/2 as ratio is less than 1 hence converges !!!
it is a geometric eries with common ratio = 1/2
S = 1/1-1/2 : 2 answer !!!!
