Write an expression for the sequence in each table.
4.
Position
1 2 3 4 5 1
Value of Term 9
10 11 12 13

Step-by-step explanation:

Determining the expression for the sequence:

Given the sequence

10,  11,  12,  13

Here, the first element is:

a₁ = 10

An arithmetic sequence has a constant difference 'd' and is defined by  

computing the differences of all the adjacent terms

The difference between all the adjacent terms is the same and equal to

now substituting d = 1 and a₁ = 10 in the nth term

Determining the value of the 9th term

Given the nth term

substituting n = 9 to determine the 9th term

Therefore, the vale of the 9th term is:

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
