The answer is 97.
53 + 11= 64
64 + 11= 75
75 + 11= 86
86 + 11= ?
64 because the series is 13, 23, 33, 43, 53, 63
64 It is a series of cubes 13, 23, 33, 43, 53 etc
64 is 53 more than 11.
The next number in the sequence is... 64
125 13 23 43 53...
13 ...23 ...33 ...43 ...53=125■
They are perfect cubes: 13, 23, 33, 43, and 53.
64 because the series is 13, 23, 33, 43, 53, 63
The sequence is the cube of successive numbers starting at 1; 13 - 23 - 33 - 43 - 53 - 63 -...
64 It is a series of cubes 13, 23, 33, 43, 53 etc
The next number in the sequence 2, 4, 16, 64 is 256.
Since 53 is a prime number and has no factors other than 1 and 53, the GCC of 53, 64, and 104 is 1.
64 is 53 more than 11.
The next number in the sequence is... 64
125 13 23 43 53...
125 (the sequence is successive numbers cubed)
117
