Answer:

The correct answer is B. -6, -5 2/5, - 4 1/5

Step-by-step explanation:

Let's find the 1st, 4th and 10th terms of this arithmetic sequence, as follows:

A(n)= -6 + (n-1) *(1/5)

A(₁)= -6 + (1 - 1) * (1/5) = -6 + (0) * (1/5) = -6

A(₄)= -6 + (4 - 1) * (1/5) = -6 + (3) * (1/5) = -6 +3/5 = -5 2/5

A(₁₀)= -6 + (10 - 1) * (1/5) = -6 + (9) * (1/5) = -6 + 9/5 = -4 1/5

The correct answer is B. -6, -5 2/5, - 4 1/5
