Describe the patter and find the next two terms of each sequence 5,1,7,0,9,-1,11

There are two interleaved arithmetic sequences here.

Odd terms are 5, 7, 9, 11, increasing by 2 each time.

Even terms are 1, 0, -1, decreasing by 1 each time.

The next two terms will be -2, 13.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
