Reducing squares 9 x 9 = 81 8 x 8 = 64 7 x 7 = 49 6 x 6 = 36 so next would be 5 x 5 = 25
The next number will be 25 because 5 times 5 = 25
Reducing squares 100 = 10² 81 = 9² 64 = 8² 49 = 7² 36 = 6² so next is 25 = 5² ---------------------------------- For the given pattern the nth term (n = 1 to 5) is given by: t(n) = n² - 22n + 121
25, 36, 49, 64, 81
Average= (36+49+64+81+100)/5 =330/5 =66
