Which equation represents the explicit formula for a constant velocity arithmetic sequence?
k0ka [10]

The equation which represents the explicit formula for a constant velocity arithmetic sequence is; Choice A; xₙ = x₁+(n-1)(v•△t).

<h3>Which equation among the answer choices represents the explicit formula for a constant velocity arithmetic sequence?</h3>

It follows from convention that an arithmetic sequence is usually defined by an expression of the form;

T(n) = T(1) + (n-1)×d in which case, d = common difference.

Consequently, in the event that the velocity in discuss is constant, it follows that the required expression is; Choice A; xₙ = x₁+(n-1)(v•△t).

Therefore, xₙ = x₁+(n-1)(v•△t) represent the equation for explicit formula for a constant velocity arithmetic sequence.

The first term of an arithmetic sequence is -3 and the fifteenth term is 53. What is the common difference of the sequence?
sertanlavr [38]

Answer:

<h2>        C)  4</h2>

Step-by-step explanation:

The nth term of arithmetic sequence is   a_n=a_1+d(n-1)

So:

    a_{15}=a_1+d(15-1)\\\\53=-3+14d\\\\56=14d\\\\d=\dfrac{56}{14}=4
