The answer is 10. The series is formed as 60 / n, where n is the position in the series. Each successive number is then formed by increasing the denominator by 1 at every step. 60 / 1 = 60; 60 / 2 = 30; 60 / 3 = 20; 60 / 4 = 15; 60 / 5 = 12; 60 / 6 = 10.
2n(n+1)
An = 2(n - 1)2 + 2(n - 1) = 2n(n - 1)

1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60.
10. The way this is derived is by dividing 60 by n (60/n). So if n is 1, then 60/n=60. Other Examples: 60/2=30 60/4=15 6th number: 60/6=10
12n = 60divide both sides integers by 12(12/12)n = 60/12n = 5=======check in original equation12(5) = 6060 = 60=======checks

If: 10N = 25 Then: N = 2.5
10 The sequence is given by xn = 60/n

n/2 = 60 Therefore, n = 60 x 2 n = 120

A pentagon has 5 sides. The perimeter is 60 so each of its sides is 60/5=12. Area = n (s/2)^2 / tan( π /n) = 5(12/2)^2 / tan ( π /5) = 247.7487
266.67 160 : 60% = n : 100% 60%n/60% = (160 * 100%)/60% n = 1600/6 n = 266.67
