Solution
The correct option is B 99
Writing the numbers in a particular arrangement we get,
1-1 , 4-1 , 9-1 , 16-1 , 25-1, 36-1, 49-1.
We can observe all the numbers are in the format of n2 - 1, where n is the number of the term in the series.
So, the tenth term in the series is 102 - 1 = 100 - 1 = 99.
