Copy and complete the table to represent the pattern in the figures. Write a rule.
Figure 1
one triangle
Figure 2
3 triangles(in a pyramid shape)
Figure 3
6 triangles(in a pyramid shape)
Thanks for your help.

Your description is unclear. If you have "3 triangles(in a pyramid shape)," there is a fourth triangle formed in the center with its apex inverted. Likewise, the "6 triangles(in a pyramid shape)" would have three inverted triangles within the figure.
However, the next level (according to your description) would have ten triangles (with six inverted triangles within the figure).
