Answer:

Step-by-step explanation:
Assuming the explicit formula is

Then f(1)=-3+2=-1
f(2)=-6+2=-4
The common difference is -4--1=-3
Then the recursive formula is given as:


Answer:
d>-150
Step-by-step explanation:
Given:
The figure of a square base pyramid.
To find:
The area of volume of the pyramid.
Solution:
The area of square base is:



Area of one triangular side of the pyramid is:



Now, the total surface area of the pyramid is:




Therefore, the surface area of the pyramid is 672 square m.
The volume of the pyramid is:

Where, B is the base area and h is the vertical height of the pyramid.
Substituting
, we get



Therefore, the volume of the pyramid is 512 cubic meters.
Hence the correct option is d.
