81
25, 36, 49, 64, 81, 100...
The next number will be 25 because 5 times 5 = 25
7^2 = 49 and 8^2 = 81
The next number is 0
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

Should there be a 16 in there somewhere? If so next three are 36, 49 and 64...
.... 49, 36, 25, 16, 9, 4 and 1
25 36 49 64 81 100 121 144
7^2 = 49 and 8^2 = 81
The next number is 0
121.
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
They are 25 and 49
81
The sequence consists of perfect squares: (3^2 = 9), (4^2 = 16), (5^2 = 25), and (7^2 = 49). The missing number corresponds to (6^2), which is 36. Therefore, the missing number in the sequence is 36.
