What is the missing value in the following sequence?
2616, 3, 11, 10850, ________, 25, 2038
In honour of the 100th Lenny Conundrum, this question was based on the answers to previous conundrums. So, the answer to Lenny Conundrum #9 was 2616, Lenny Conundrum #16 was 3, Lenny Conundrum #25 was 11, Lenny Conundrum #36 was 10850, Lenny Conundrum #49 was "Abracadabra", etc.
The sequence goes by square numbers (9,16,25,36,49,64,81). Interestingly, the next item in the sequence would have been "Abracadabra" also!
