Use the iterative rule to find the 11th term in the sequence.

an = 18 – 2n

-4

Step-by-step explanation:

The general, nth term, of a sequence is given by the formula:

We can plug in n = 1 to find the first term, thus we have:

We can plug in n = 2, to the find the 2nd term, which is:

Similarly, to get 11th term, we simply plug in n = 11 into the general term rule. so we have:

11th term is -4

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

thus, the first answer choice, y = sec x, is the correct one
