I got you , it’s option 4 .
Answer:
= (3n + 7)
Step-by-step explanation:
We require to find the first term a₁ and the common difference d
The n th term is given by 3n + 2, thus
a₁ = 3(1) + 2 = 3 + 2 = 5
a₂ = 3(2) + 2 = 6 + 2 = 8
d = 8 - 5 = 3
= [ 2a₁ + (n - 1)d ], substitute values
= [ (2 × 5) + 3(n - 1) ] = (10 + 3n - 3) = (3n + 7)
What is the problem that you are talking about
Steps to solve:
-12x - 2(x + 9) = 5(x + 4)
~Distribute
-12x - 2x - 18 = 5x + 20
~Combine like terms
-14x - 18 = 5x + 20
~Add 18 to both sides
-14x = 5x + 38
~Subtract 5x to both sides
-19x = 38
~Divide -19 to both sides
x = -2 (Option B)
Best of Luck!
