Determine whether the sequence is an arithmetic sequence.
Answer to Problem 10PPS
No, this is not an arithmetic sequence
Explanation of Solution
Given:
The sequence:
Concept Used:
An arithmetic sequence is a list of numbers with a definite pattern. If you take any number in the sequence then subtract it by the previous one and the result is always the same or constant then it is an arithmetic sequence.
In an Arithmetic Sequence the difference between one term and the next is a constant.
Calculation:
The sequence:
First term = − 10 and the second term is − 7
Difference between second term and first term is
Second term = − 7 and the third term is − 4
Difference between third term and second term is
Third term = − 4 and the fourth term is 1
Difference between 4th term and 3rd term is
This is not an arithmetic sequence. The difference between terms is not constant.
Thus, no, this is not an arithmetic sequence.

- M = log The formula determines the magnitude of an earthquake, where / is the intensity of the earthquake and S is the intensity of a "standard earthquake." How many times stronger is an earthquake with a magnitude of 8 than an earthquake with a magnitude of 6? Show your work.arrow_forwardNow consider equations of the form ×-a=v = √bx + c, where a, b, and c are all positive integers and b>1. (f) Create an equation of this form that has 7 as a solution and an extraneous solution. Give the extraneous solution. (g) What must be true about the value of bx + c to ensure that there is a real number solution to the equation? Explain.arrow_forwardThe equation ×+ 2 = √3x+10 is of the form ×+ a = √bx + c, where a, b, and c are all positive integers and b > 1. Using this equation as a model, create your own equation that has extraneous solutions. (d) Using trial and error with numbers for a, b, and c, create an equation of the form x + a = √bx + c, where a, b, and c are all positive integers and b>1 such that 7 is a solution and there is an extraneous solution. (Hint: Substitute 7 for x, and choose a value for a. Then square both sides so you can choose a, b, and c that will make the equation true.) (e) Solve the equation you created in Part 2a.arrow_forward
