In order to determine the total points scored by Jeremy's quarterback, we simply need to multiply the actions performed by the quarterback with the pointing system. In this case we have the following equation:

(6)(2) + (0.5)(16) + (-0.5)(7) + (-1.5)(2) =  13.5

Thus, Jeremy's quarterback scored a total of 13.5 points in one game.

The next term in a sequence Comes from adding the
Leno4ka [110]

Answer:

Step-by-step explanation:

Each new term is the sum of the two preceding terms.  Given 2, 9, etc., we see that a number between 2 and 9 is missing; call it x.  Then 2 + x must equal 9, and so x = 7, and so the first three terms are 2, 7, 9.  Repeating the process, we add 7 and 9, obtaining 16; thus the first four terms are 2, 7, 9, 16.  Continuing this pattern, we add 9 and 16 to obtain the fifth term, which is 25:  2, 7, 9, 16, 25.  And so on.
