Reversing the digits of the numbers we get,
81, 64, 49, 36, 25.
These are the squares of numbers,
9, 8, 7, 6, 5.
Hence the next number will be the
square of 4. which is 16.
Reversing digits again the answer is 61.
Hence option no. 6.

swap the no. in 18, it will become 81
similarly we get 64, 49, 36, 25..... these are perfect square of natural numbers in decreasing order so next will be 16. so swap the no.'s and we will get our final answer that is 61...

The first digit of the no. Is last term of the square like 1^2=1,2^2=4,3^2=9,4^2=16=6(last digit),5^2=25=5,hence first digit of required no. is 6^2=36=6,and the second digit is going to decrease like 8,6,4,3,2,hence second digit of the required no. is 1 Hence no. is 61
