Answer:The pattern in this sequence is that each term is multiplied by 2x to get the next term. Here's how it works: - Start with 2x- Multiply by 2x: 2x * 2x = 4x²- Multiply by 2x: 4x² * 2x = 8x³- Multiply by 2x: 8x³ * 2x = 16x⁴- And so on... Therefore, the sequence is a geometric sequence with a common ratio of 2x.
