Question

Which one would it be?

Answer 1

c

Explanation:

the sequence has a common difference between consecutive terms, that is

a₂ - a₁ =4x + 3 - (3x + 4) = 4x + 3 - 3x - 4 = x - 1

a₃ - a₂ = 5x + 2 - (4x + 3) = 5x + 2 - 4x - 3 = x - 1

Thus the sequence is arithmetic with common difference d = x - 1
