Step-by-step explanation:
a1 = - 7
d = 4
an = a1 + (n - 1) * d
an = - 7 + (n - 1) * 4
an = - 7 + 4n - 4
an = -11 + 4n
Try this out. Let n = 3
a3 = -11 + 4*3
a3 = - 11 + 12
a3 = 1 Which is what the series says.

Hi,
The volume of the cylinder is :
V = π × r^2 × h
V = 3,142 × (2)^2 × 5
V = 62, 8319 cm^3
π : Pi => 3,142
r : radius of the cylinder (2 units).
h : height of the cylinder (5 units).
The base of the cylinder is a circle , so to calculate the area we have to use the formula : area = π × r^2. And to find the volume , we have to multiply the area by the height.
