Explanation:
The formula for the counting rule of an experiment with k-steps with
outcomes each. This is a process of randomly selecting k numbers (or objects) with replacement (or repetition). Look for the formula in your notes, PowerPoint slides or textbook.
- For the first step you have:
posibble outcomes
- For the second step you have:
posibble outcomes
- For the third step you have:
posibble outcomes
- For the k-step you have:
posibble outcomes
Thus, a per the Fundamental Counting Principle or counting rule, the number of possible outcomes is:

That is
multiplied by itself k time, which is
raised to power
.

Answer:
So in this sequence, we are adding by 9 in each term
So our pattern is: 7 , 7 +9 , 7 + 2(9) , 7 + 3(9) .....
hence, we can write it as: 7 +
where n is the number of the term you want
The expression 3P2 can also be read as "permutation of 3 taken 2". This represents the number of ways in which the 3 items are arranged with the emphasis on the arrangement of the first two other items.
