DERET 5 1 1 9 2 2 13 3 3

Speed= (frequency) x (wavelength)
= (2 per second) x (5 cm) = 10 cm/sec .

The speed of the wave is calculated using the formula v = f × λ . In this case, with a wavelength of 5 cm and a frequency of 2 Hz, the speed comes out to be 10 cm/s. Therefore, the wave speed is 10 cm/s .

Jawab:Penjelasan dengan langkah-langkah:The provided sequence "DERET 5 1 1 9 2 2 13 3 3" does not follow a standard mathematical pattern like the Fibonacci sequence or a simple arithmetic progression. It appears to be a combination of different sequences or a random arrangement of numbers.Here's a breakdown of why it's not a standard sequence: Fibonacci Sequence:The Fibonacci sequence starts with 0 and 1, and each subsequent number is the sum of the two preceding ones (e.g., 0, 1, 1, 2, 3, 5, 8...). This sequence doesn't follow that pattern.Arithmetic Progression:An arithmetic sequence has a constant difference between consecutive terms (e.g., 2, 4, 6, 8...). The differences in the given sequence (4, 0, 8, -7, 0, 11, -10, 0) are not constant.Possible Combinations:It's possible the sequence is a combination of different sequences or a deliberate arrangement. For example, it could be:Two separate sequences combined: One sequence might be 5, 9, 13, 17... (adding 4) and the other 1, 2, 3, 4... (adding 1). The given sequence would then be a mixing of these two.A sequence with a repeating pattern: There could be a pattern in how the numbers are grouped or repeated, but without further information, it's difficult to determine.A random sequence: It's also possible the sequence is simply a random arrangement of numbers, without any underlying mathematical rule.In conclusion, without more context or a clear pattern, it's challenging to determine the "DERET" of the sequence..
