Answer:
x = 7
Explanation:
8 + 4 = 2 (x − 1)
Simplify both sides of the equation
8 + 4 = 2(x − 1)
8 + 4 = (2)(x) + (2)(−1) (Distribute)
8 + 4 = 2x + −2
(8 + 4) = 2x − 2 (Combine Like Terms)
12 = 2x − 2
12 = 2x − 2
Flip the equation
2x − 2 = 12
Add 2 to both sides
2x − 2 + 2 = 12 + 2
2x = 14
Divide both sides by 2
2x / 2 = 14 / 2
x = 7

Step-by-step explanation:
Answer:
Option B
Step-by-step explanation:
First term of the given arithmetic sequence 'a' = -3
Common difference in each successive term 'd' = -8 - (-3)
d = -5
Explicit formula for an arithmetic sequence will be,

Here, n = number of term
= nth term of the sequence

For n = 23,
= -3 + (23 - 1)(-5)
= -3 - 110
= -113
Option B is the answer.
