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.
Hey I hope this helps you
You first need to move everything to one side to equal zero.
Then factor out the 5
After you should be left with a quadratic equation easier to work with
What multiplies to 30 and adds to -11?
This would be 6 and 5
But since it is -11 those two numbers need to be negative as well
