Which one of these formulas describes the following sequence?<br><br> 1,5,12,22,35
kati45 [8]

We can find a formula for nth term of the given sequence as follows:

1, 5, 12, 22, 35

The 1st differences between terms:

4, 7, 10, 13

The 2nd differences :

3, 3, 3

Since it takes two rounds of differences to arrive at a constant difference between terms, the nth term will be a 2nd degree polynomial of the form: a n^2 + b n + c, where c is a constant. The coefficients a, b, and the constant c can be found.

We can form the following 3 equations with 3 unknowns a, b, c:

1 = a\cdot1^2 + b\cdot1 + c\\5 = \cdot2^2 + b\cdot2 + c\\12 = a\cdot3^2 + b\cdot3 + c

Solving for a, b, c, we get:

a = 3/2, b = -1/2, c = 0

Therefore, the nth term of the given sequence is:

\boxed{ a_n = \dfrac{3}{2}n^2- \dfrac{1}{2} n}

Help with algebra problem

Answer:

Yes

Step-by-step explanation:

To find the answer, you just have to plug the (x,y) values into the equation to see if it is true.

3(1) > 5(-6) -12

3 > -30 -12

3 > -42

Since 3 > -42 the ordered pair is a solution to the inequality

Multiply the probability by the cost of the accident:


14,886.05 x 0.071 = 1056.91

Now add the overhead cost:

1056.91 + 110 = 1166.91

The closest answer to this is number D.
