MULTIPLE CHOICE QUESTION
1 min • 1 pt
Which function represents the sequence?
f(n) = n + 3
f(n) = 7n - 4
f(n) = 3n + 7
f(n) = n + 7
Answer explanation
Just think of the pattern as if it was a table!
----- ----- ----- -----
Final answer will look like:
f(n) = a0 + (d)(n)
----- ----- ----- -----
Step 1: Find "d"
Subtract an values backwards
I will pick last two numbers
d = 31 - 24 = 7
----- ----- ----- -----
Step 2: Find "a0"
Only one answer choice has correct "d" value so we don't need to find "a0" value here
----- ----- ----- -----
f(n) = -4 + 7n
f(n) = 7n - 4

MULTIPLE SELECT QUESTION
1 min • 1 pt
Which two functions represent the sequence?
f(n) = n + 3
f(n) = 7n - 4
f(n) = 3 + 7(n - 1)
f(n) = 7 + 3(n - 1)
Answer explanation
Final answer will look like:
f(n) = a0 + (d)(n)
f(n) = a1 + (d)(n - 1)
----- ----- ----- -----
We already found one answer
f(n) = a0 + (d)(n)
f(n) = -4 + 7n
----- ----- ----- -----
Find second answer
f(n) = a1 + (d)(n - 1)
f(n) = 3 + 7(n - 1)
