Find the first four terms of the sequence using the recursive formula. ​
frozen [14]

Answer:

- 3, - 11, - 35, - 107

Step-by-step explanation:

Using the recursive formula with f(1) = - 3 , then

f(2) = - 2 + 3f(1) = - 2 + 3(- 3) = - 2 - 9 = - 11

f(3) = - 2 + 3f(2) = - 2 + 3(- 11) = - 2 - 33 = - 35

f(4) = - 2 + 3f(3) = - 2 + 3(- 35) = - 2 - 105 = - 107

Thus the first four terms are

- 3, - 11, - 35, - 107

What is x?<br><br> 4(x - 4) + 65 = -3x
svet-max [94.6K]
    4(x - 4) + 65 = -3x
4(x) - 4(4) + 65 = -3x
     4x - 16 + 65 = -3x
            4x + 49 = -3x
          - 4x           - 4x
                    49 = -7x
                    -7      -7
                     -7 = x
