Final answer:

The limit of the sequence x₍ = 3n³+2n−1/n³-n+2 is found by dividing the leading coefficients, which results in the limit being 3 as n approaches infinity.

Step-by-step explanation:

To find the limit of the sequence x₍ = 3n³+2n−1/n³-n+2 as n approaches infinity, we look at the highest powers of n in the numerator and the denominator. Here, the highest power is in both. So, the limit can be found by dividing the coefficients of the highest power terms in the numerator and the denominator.

The leading term in the numerator is 3n³ and the leading term in the denominator is n³. Therefore, the limit of the sequence x₍ as n approaches infinity is the coefficient of in the numerator divided by the coefficient of in the denominator, which is 3/1 or simply 3.
