Answer:

a7 = 12,  a11= 47

Step-by-step explanation:

768, 384, 192, 96, 48, 24, 12

a(n) = 768 / (2∧X - 1)

a(7) = 768 / 2∧6 = 768 / 64 = 12

7, 11, 15, 19 23, 17, 31, 35, 39, 43, 47

a(n) = 7 + 4 * (X-1)

a(11) = 7 + 4 * (11-1) = 7 + 40 =47

Use the formula to evaluate the series 3-9+27-81+...-a8
Andrej [43]

In the given series, we see that the first term is 3 and the common ratio between the succeeding terms is -3. To solve for the sum of the first 8 terms, we use the equation,

                                    Sum = (a1)(1 – r^n) / (1 – r)

Substituting the known terms,

                                    Sum = (3)(1 – (-3)^8)/(1 - -3) = -4920

<span>Thus, the answer is -4920.</span>
