1x2x4x8x
1x2x4x8x refers to a sequence of numbers where each term is obtained by multiplying the previous term by 2. This sequence is a specific instance of a geometric progression. The first term is 1, and the common ratio is 2. Therefore, the sequence can be represented as 1 * 2^n, where n starts from 0.
The terms of the sequence are generated as follows:
The first term is 1 (1 * 2^0).
The second term is 2 (1 * 2^1).
The third term is 4 (1 * 2^2).
The fourth term is 8 (1 * 2^3).
The fifth term would be 16 (1 * 2^4).
The notation "1x2x4x8x" itself suggests a pattern of multiplication, where "x" might indicate the continuation of
