I believe the answer is c or 3
Answer: Choice C. an = 8 + 9(n-1)
===========================================
Work Shown:
a1 = 8 is the first term
a7 = 62 is the seventh term
an = a1+d(n-1) = nth term of arithmetic sequence
a7 = a1+d(7-1) ... plug in n = 7; solve for d
62 = 8+d(6)
62 = 6d+8
6d+8 = 62
6d = 62-8
6d = 54
d = 54/6
d = 9 is the common difference
an = a1 + d(n-1)
an = 8 + 9(n-1) is the nth term of this arithmetic sequence
Each tube of paint costed Mez $6.
•••Step by step:
70-16= 54 ( You would subtract 16 from 70 to find out what the price of all 9 tubes of paint were.)
54/9=6 ( to find the cost of each tube, you would divide 54 by 9 since the total cost was $54 and she bought 9 tubes this would divide the number 54 equally between each tube to find out the cost of a single tube, which is $6.)
You will substitute x with -2 so the answer will be -8
