a) <u>n² + 6 </u>
~Here n is the number of term. So, put n = 1,2,3,4.... to get the term.
- If n = 1, first term = 1² + 6 = 7
- n = 2, second term = 10
- n = 3, third temm = 15
- n = 4, fourth term = 22
- n = 10, tenth term = 106
b) <u>3n²</u>
- If n = 1, first term = 3
- n = 2, second term = 12
- n = 3, third term = 27
- n = 4, fourth term = 48
- n = 10, tenth term = 300
Answer: Step 5
===================================================
Reason:
The order of operations is PEMDAS
- P = parenthesis
- E = exponents
- M = multiplication
- D = division
- A = addition
- S = subtraction
The multiplication and division are on the same level of precedent, and the same goes for addition and subtraction. Some math textbooks may refer to PEMDAS as BODMAS, which is basically the same thing.
Notice how division comes before addition. So we must compute the 
portion first before adding in step 4.
This is what steps 4 and onward should look like
So that's why the error is in <u>step 5</u>
If there was parenthesis around the "2+10", and we had 
, then step 5 given by your teacher would be correct.

To obtain the sample, one can choose the names of 6 students out of a hat from the students in the class using random sampling.
<h3>What is random sampling?</h3>
It should be noted that a simple random sample is a subset of a statistical population where each member of the subset has an equal probability of being chosen.
Systematic sampling is when the sample members from a larger population are selected based on a fixed, periodic interval. If you want to select a random group of 6 students from a population of about 60 using systematic sampling, every 10th person on the list is selected.

Assuming that f(n+1) = f(n) is the full recursive definition, and that there are no typos, then this means that the nth term is equal to the (n+1)th term for any n where n is a positive whole number.
So
f(1) = f(2)
f(2) = f(3)
f(3) = 9
By the transitive property, f(1) = f(3) = 9. Therefore the answer is 9.
