f(1) = 2; f(n) = f(n-1) + 7

f(2) = (2-1) + 7 = 1 + 7 =8

f(3) = (8-1) + 7 = 7 + 7 =14

f(4) = (14-1) + 7 = 13 + 7 =20

f(5) = (20-1) + 7 = 19 + 7 =26

and so on...so it's increase by 6

f(6) = 26 + 6 = 32

f(7) = 32 + 6 = 38

f(8) = 38 + 6 = 44

f(9) = 44 +6 = 50

f(10) = 50 + 6 = 56

<em>Cross out all outer numbers</em>

We are left with 17 and x

With double medians, you add those two together and then divide them by two.

With the median (total) being 18, we will first add 17+x then divide Y/2 = 18

The value of x is 1
