Pascal's TriangleCan you find the Fibonacci sequence in the triangle?

Any individual term, let's say the ith term, in a binomial expansion can be represented like this:

Example: Find the 4th term in the expansion of

Recall: This relation holds for each term in any binomial expansion:

Example: Find the term that contains x in the expansion of

[exponent on a] + [exponent on b] = n

And any individual term in a binomial expansion can be represented like this:

Recall: This relation holds for each term in any binomial expansion:

Example: Find the term that contains x in the expansion of

[exponent on a] + [exponent on b] = n

And any individual term in a binomial expansion can be represented like this:

Recall: This relation holds for each term in any binomial expansion:
