1)
u have a mistake in the question because n = 42 + 3-3 = 42 which u haven't included in the options.

2)
median means number in the middle when you arrange in order
12, 5, 23, 17, 15, 9, 14 ----> 5, 9, 12, 14, 15, 17, 23
u can see that 14 is in the middle

3)
u have to brainstorm yourself to get y in terms of x, or you can graph it
the formula u want is y = mx + b
i found y = 3x - 2 to be an exact match for all numbers.

4)
pythagorean theorem --------> a^2 + b^2 = c^2; c is hypotenuse, a&b are the short sides of the right angled triangle
so, 20^2 + 30^2 = c^2; c = 36.05
so, the closest thing is A
