Question

Identify the 35th term of an arithmetic sequence where a1 = -7 and a18 = 95. (2 points)

Question 1 options:

1) 203

2) 197

3) 168

4) 163,

Answer 1

Answer: 197

Step-by-step explanation: I took the test :)))

Answer 2

Arithmetic sequences have the same value added repeatedly. There are 17 increments between a1 and a18 and the value changes a total of 102 (95 - -7). 102 divided by 17 shows that the value of 6 is being added each time. The 35th term is then given by a1+(35-1)*6 = -7 + 34*6 = -7 + 204 = 197.
