The answer of this question is gonna be A
We have been given that a colleague has been tutoring six students in 11th grade to prepare for the ACT. Student scores were as follows: 20, 18, 16, 15, 23, 20. We are asked to find the mean of the ACT scores.
We will use mean formula to solve our given problem.




Upon rounding to nearest whole number, we will get:

Therefore, the mean of the ACT scores is 19 and option 'c' is the correct choice.
Answer:
This is a sequence where you <em>multiply that number 3 times</em>. For example, 2 x 3 = <em>6</em>. 6 x 3 = <em>18</em>. 18 x 3 = <em>54</em> and so on. Therefore, <em>multiplying 3 by the number is the Answer.</em>
