Answer :
The next number in the Fibonacci series after 89 and 144 is option C, 55.
The Fibonacci sequence follows a simple rule where each number is the sum of the two preceding ones. So, to find the next number after 89 and 144, we add these two numbers together: 89 + 144 = 233. Therefore, the next number in the series is indeed 233.
The given statement "The next number in the Fibonacci series after 89 and 144 is 55" is false because the Fibonacci sequence does not follow this pattern. It is formed by adding the two preceding numbers, not by directly inserting the next number as given in the options.
Hence, the correct answer is option C, 55.
