Today is day 4 of the problem of the week. Good luck!
Easy: Take the following sequence:
6, m, n, e, h, ...
You may notice a letter in there that you haven't seen yet: n. I want you to determine the value of n.
Hint: Look for common differences.
Hard: Today's part will take a little longer than usual, but shouldn't be too bad.
First, figure out the following equations:
a = 10z/t
b = -t(9s - 7t - 10)/z
c = (t ÷ z ÷ s)^-8
Remember the order of operations (which are listed on yesterday's post).
You might be wondering why I chose a, b, and c. It is because you then have to solve for x in this equation:
0 = ax^2 + bx + c.
Hint: You can use any of the methods to solve quadratic equations you wish. The most straight forward is the quadratic formula which is below.
x = [-b ± √(b^2 - 4ac)]/2a
