Question

Write a function f(b) that determines the number of
triangles in any given level of the pyramid.

Answer 1

Answer:

  f(l) = l/3

Step-by-step explanation:

A clue to the functional relation is often found in the differences between values in the table.

Here the differences between "level" values are all 3. The differences between "triangles" values are all 1. The constant differences suggest the relation is linear. We note that all "triangles" values are 1/3 the "level" values.

  f(l) = (1/3)l
