Answer:
f(n) = -11 + 22(n - 1)
<em>f(1) is your initial value.</em>
f(1) = -11 + 22(1 - 1)
f(1) = -11
------------------------------------------------------------
f(2) = -11 + 22(2 - 1) = 11
f(3) = -11 + 22(3 - 1) = 33
f(4) = -11 + 22(4 - 1) = 55
<em>f(n - 1) is just a notation for the previous term</em>
<em>Using the equation f(n) = f(n - 1) + _______ :</em>
f(2) = f(1) + ??? = 11
f(3) = f(2) + ??? = 33
f(4) = f(3) + ??? = 55
f(2) = -11 + ??? = 11
f(3) = 11 + ??? = 33
f(4) = 33 + ??? = 55
f(2) = -11 + 22 = 11
f(3) = 11 + 22 = 33
f(4) = 33 + 22 = 55
∴ f(n) = f(n - 1) + 22

Answer:
12
Step-by-step explanation:
The hypotenuse of a 45-45-90 triangle is equal to the length of a leg times 
So, in your problem,

= 6(2) = 12
Answer:
54
Step-by-step explanation:
92 - 38 = 54
or
90 - 36 = 54
Answer:
67.17
Step-by-step explanation:
First, identify the hundreds digit (the 7)
Next, identify the next smallest place value (the 1)
Then, determine if 7 greater than or equal to 1. Yes, it is greater than 1, so round up. Increase the hundreds digit by one, so 7 becomes 8.
Finally, keep .17 and you get an answer of 67.17.
