The total of two whole numbers one after another is 33. for example 10 + 11 (two consecutive integers) = 21
The answer would be 3n^2 + 2.
This can be found/proven by replacing "n" with term number (1,2,3,4...), then solving to get the final number. For example 3 * 1^2 + 2. You would first do 1^2, which is 1. Next, you would multiply 1 by 3, to get 3. Finally, you'd and the 2 to get 5. 5 is the 1st term, and you can use this same equation to get the rest of the terms you need.
I hope this helps!
$29.40 ........ 40x0.3=12....... 40-12=28...... 28x1.05= $29.40
Negative exponents work like this:

So, you have

This number is less than 1, so she will play tennis.
I would think the value would be .2 cause if you had 100 tosses you would expect 60 value for heads and -40 value for tails. giving you 20/100
