Answer:
Option C) 
for 
is not the correct way to define the given infinite sequence
Step-by-step explanation:
Given infinite sequence is
Option B) for is not the correct way to define the given infinite sequence
Now verify for is true for the given infinite sequence
That is put n=1,2,3,.. in the above function
When n=1, 
When n=2, 
When n=3, 
and so on.
Therfore for is not the correct way to define the given infinite sequence
Therefore option C) is correct
Like terms are terms that have the same variable no matter the coefficient value such as a negative or positive coefficient (number right to left of the variable aka the letter representing an unknown amount of value).
A. 8n : - 4n becuase the have the same variable (N)
B. - 2d: D because they have the same variable and even if d has no coefficient, it still has value, variables with no coefficient always equal 1 no matter the circumstances
C. - b: 17b and -3b2 because they both have the same variable eliminating the coefficients being two different types of numbers (positive and negative). The expressions have to have the same variable.
D: 4y², -3y2,4y, and 4 to the second power. This is because they all have the same variable.
E. 6x2y: 3xy because the variable are specifially xy and they must be in order to be like terms.
abc: all because they have all the letters but are just in different orders of variables. (thats all)
