anonymous · Answer

simply
(n+1)th perimeter=nth perimeter+5
where n is the number of triangles ....

cwrw238 · Answer

right its an arithmetic series with  first term 17 and common difference 5

so for example the 5th triangle will  have a perimeter 17 + (5-1)* 5 =  37

anonymous · Answer

ooooooooooh! I see it now.

cwrw238 · Answer

good

cwrw238 · Answer

the perimeter increases by 5 every time
5 is called the common difference

anonymous · Answer

Write the equation that represents the relationship between n the number of triangles and p the perimeter of the figures formed.

cwrw238 · Answer

p = 17 + 5(n -1)
