Understanding Geometric Sequences

The video tutorial explains a sequence where each term is twice the previous one, starting from one. It demonstrates how to express terms as powers of two and calculates the 16th, 17th, and 18th terms. The tutorial then shows how to sum these terms and simplify the result using factorization, concluding with the final answer.

What is the first term of the sequence described in the video?

• 1

• 2

• 4

• 8
