100. the pattern is 7 squared, 8 squared, 9 squared....
25 36 49 64 81 100 121 144
.... 49, 36, 25, 16, 9, 4 and 1
These are square numbers of 3, 4, 5 with alternating sign, I'd expect to continue the sequence with 36, -49, 64, -81, 100
This sequence is the squaring of the numbers 1, 3, 5, and 7. The next number is 9^2 = 81.
49
144
25, 36, 49, 64, 81, 100...
81

121.
25 36 49 64 81 100 121 144
The next number will be 25 because 5 times 5 = 25
The first thing to notice is that all the numbers in the sequence are square numbers. 25=5x5 36=6x6 49=7x7 64=8x8 81=9x9 So the next three numbers to be squared are 10, 11 and 12. 10x10=100 11x11=121 12x12=144 Thus, the next three numbers in the sequence are 100, 121, 144 The equation for the sequence is (n+4)2
.... 49, 36, 25, 16, 9, 4 and 1
The next number is 48.
The given number sequence is a series of perfect squares: 7^2, 8^2, 9^2, 10^2. Therefore, the next number in the sequence would be 11^2, which is 121.
