The next number will be 25 because 5 times 5 = 25
25 36 49 64 81 100 121 144
7^2 = 49 and 8^2 = 81
121.
81
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
36 - The sequence is deducting two from the difference between the two numbers each time.81-64=1764-49=15 therefore49-36=13It is squire of numbers in decending order9*9=818*8=647*7=496*6=36
