Complete the recursive formula of the geometric sequence -0.3, 0.9, -2.7, 8.1. ....

Answer:

(-1)ⁿ(3)ⁿ/10

Step-by-step explanation:

The first term a = 0.3, the second term, ar = 0.9. The common ratio r = ar/a = 0.9/-0.3 = -3.

From the general term of a geometric series,

U = arⁿ⁻¹

= (0.3)(-3)ⁿ⁻¹

= (3/10)(-3)ⁿ⁻¹

= (-1)ⁿ⁻¹(3)(3)ⁿ⁻¹/10

= (-1)ⁿ(3)ⁿ/10

Answer :

Length of rectangle = 14m

Width of rectangle = 12m

Explanation :

p = 2l + 2w = 68

l = w + 2

Substitute:

68 = 2(w + 2) + 2w

68 = 2w + 4 + 2w

4w = 64

w = 16

l = 18
