For each positive integer $n$ consider the set $S_n$ defined as follows: $S_1 = \{1\},\:S_2 = \{2, 3\},\:S_3 = \{4,5,6\}, \: \dots $ and in general, $S_{n+1}$ consists of $n+1$ consecutive integers the smallest of which is one more than the largest integer in $S_n$. Then the sum of all the integers in $S_{21}$ equals to $1113$ $53361$ $5082$ $4641$

GATE IT 2006 | Question: 68
On a wireless link, the probability of packet error is $0.2$. A stop-and-wait protocol is used to transfer data across the link. The channel condition is assumed to be independent of transmission to transmission. What is the average number of transmission attempts required to transfer $100$ packets? $100$ $125$ $150$ $200$
