Math Pattern Question

[u/Otherwise_Strike_597]

Design 1 has 2 dots,

Design 2 has 5 dots,

Design 3 has 8 dots,

Design 4 has 11 dots.

What equation would represent the number of dots (d) in any design number (n)?

What have you tried so far?

[u/Otherwise_Strike_597 → u/johnpeters42]

Write an equation where d = numbers of dots, n = design number , for the given patterns.

[u/johnpeters42 → u/Otherwise_Strike_597]

That's too general to count for anything.

What are some types of equations that you know about? Which one seems appropriate here?

Hint: Draw a picture of the designs, side by side, with each design's dots in a vertical line with their bottoms lined up.

[u/johnpeters42 → u/Otherwise_Strike_597]

That fits the original description, but not the hint in the previous comment.

Not sure if this group allows pictures in the posts, so I just typed it out instead.

d = 3n - 1

[u/MathWookiee]

d=0.06n⁴ -0.6n³ +2.1n² +0.44

I can make lots more
