What expression shows the relationship between the value of any term and n, its position in the sequence for the given sequence? 10, 5, 0, -5, -10, a) -5n b) -5n + 15 c) -3n + 15 d) 5n

B

Step-by-step explanation:

These are the terms of an arithmetic sequence with n th term

= + (n - 1)d

where d is the common difference and the first term

here d = - 10 - (- 5) = - 5 - 0 = 0 - 5 = - 5 and = 10, hence

= 10 - 5(n - 1) = 10 - 5n + 5 = 15 - 5n → B

7. d. 64

8. i. 32

9. c. 125

10. j. none of the above

11. d. 81

12. i. 216

13. e. none of the above

14. g. 240

15. e. none of the above

16. g. 32

17.   e. none of the above
