Answer:

2, 5, 8, 11, 14

Explanation:

William has created a sequence of five numbers. His rule is to add the same number each time. The number that William was adding to each number was the number three. I found this out by adding 3 to 2, and I got 5. Next, I added 3 to 5, and I got 8. I did it again for a third time and added 3 to 8, and I got 11. Lastly, I added 3 to 11 and I got 14, which completes the number sequence the way that William explained it. I hope this helped you and didn’t make it more confusing for you. I put an example below just for an easy reminder.

How do you find the surface area of a regular triangular prism

Dmitry [639]

So a triangular prisim is like a triangle stacked on top of x number of identical triangles making a height, like a piece of paper made into a stack

so
basically find the area of each side and add

look at diagram/attachment
find area of triangle
1/2 b times h= area of 1 triangular face

multiply by 2 because 2 sides so 1/2 times 2 b times h=b times h

then 3 other sides
find area of each side and add
areas=(H times B)+(H times c)+(H times a)

so SA=(b times H)+(H times B)+(H times c)+(H times a)
