POM TRI Triangles & Sequence RULE Question. Please help

Jo constructs triangular patterns using dots.

Pattern 1 (has 3 dots forming a triangle)

Pattern 2 (has 6 dots forming a larger triangle)

Pattern 3 (has 10 dots forming an even larger triangle)

The pattern continues in the same geometric design.

How many dots are needed for the nth pattern?

Jo was born in 1953, she was wondering if she could make a triangular pattern out of exactly 1,953 dots. If she could, what would the pattern number be?

THANKS!
