What is the nth term of the arithmetic sequence 7, 9, 11, 13, 15, 17, . .? a. 3n+4 b. 4n+3 c. n+2 d. 2n+5 Arithmetic Sequence Finding the nth term: The nth term of the arithmetic sequence 7, 9, 11, 13, 15, 17, . . is 2n + 5. Solution: 1. Given the following: a₁ = 7 a₂ = 9 a₃ = 11 a₄ = 13 a₅ = 15 a₆ = 17 2. Solve for d. d = a₂ – a₁ d = 9 – 7 d = 2 3. Solve for the nth term. a_n = a₁ + (n - 1) d a_n = 7 + (n – 1) 2 a_n = 7 + (2n – 2) a_n = 2n + (7 – 2) a_n = 2n + 5 4. Therefore, the nth term of the arithmetic sequence 7, 9, 11, 13, 15, 17 , . .is 2n + 5. Definition: An arithmetic sequence is a sequence of numbers such that the difference of any two consecutive terms of the sequence is a constant. While an arithmetic series is the sum of the terms of the arithmetic sequence. Code: 10.3.1.1 For more details on arithmetic sequence, got to the following links: brainly.ph/question/5...
What is the next number? What is the 7th number? 160, 80, 40, 20, 10, _____ Answer: The next number is 5. The complete sequence then becomes 160, 80, 40, 20, 10, 5 . Step-by-step explanation: To find out the the missing number in the given sequence, you have to discover the pattern that is being applied in the sequence. If you can notice, the next number is always half of the previous number. For example, the first term is 160, and the second term is 80 because 80 is the half of 160. The next term is 40 because 40 is the half of 80. The next term is 20 because 20 is the half of 40. The next term is 10 because 10 is the half of 20. The last term is therefore 5 because 5 is the half of 10. Therefore, the answer is 5, and the complete sequence is 160, 80, 40, 20, 10, 5 .

What do you call the given equations? Polynomial Equation: A polynomial equation is any polynomial equated to zero. Examples: x - 2 = 0 x² + 2x + 5 = 0 5x + 1 = 0 x³ - 2x² - 4x + 8 = 0 x(x - 4) = 0 Number of Roots: The number of root(s) of the polynomial equation is based on the highest degree of the exponent it contain. Example #1: x - 2 = 0 the number of root(s) is just 1 since it is a polynomial of the first degree. Example #2: x² + 2x + 5 = 0 the number of root(s) is 2 since it is a polynomial of the second degree. Example #3: 5x + 1 = 0, there is only 1 root because it is a polynomial equation of the first degree. Example #4: x³ - 2x² - 4x + 8 = 0 have 3 roots since its highest degree is 3. Example #5: x(x - 4) = 0 have 2 roots because it is a polynomial equation of the second degree.
