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:
, 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:

Solving for a, b, c, we get:
a = 3/2, b = -1/2, c = 0
Therefore, the nth term of the given sequence is:

Poorly formulated question. Please provide a question as I am confused what you are asking.
3. (t^2) - 4
4. (1/5)*s + 4
Try C but im not 100% sure though
The probability that the result that is gotten will be a multiple of 3 and 2 will be 2/15.
<h3>How to calculate the probability</h3>
From the information, the spinner has 15 equal areas, numbered 1 through 15.
The multiple of 3 and a multiple of 2 among the numbers will be 6 and 15. Therefore, the probability will be two out of fifteen. This will be 2/15.
