# What should be the next number in the following series? 100, 96, 104, 88, 120, 56,…?

Answer: The next number should be 136.

## Sequences and Series

Understanding patterns in sequences and series is a fundamental aspect of mathematics. This particular series alternates between subtracting and adding multiples of 8 (100-4×8, 96+8×8, 104-2×8, 88+4×8, 120-8×8). Following this pattern, the next operation would be adding 8×8 to 56, resulting in 136. Recognizing patterns and predicting the next number in a series is not only a key mathematical skill but also critical in various scientific and economic analyses where trends and forecasts are made based on historical data.
