Question

question #4
what is the missing value on the bell curve below?
38 41 44 47 50 53?
54
55
56
57

Explanation:

Step1: Find the common difference

Calculate the difference between consecutive known values. For example, \(41 - 38=3\), \(44 - 41 = 3\), \(47-44 = 3\), \(50 - 47=3\), \(53 - 50=3\). The common difference \(d = 3\).

Step2: Calculate the missing value

Since the pattern is an arithmetic sequence (common difference \(d = 3\)), and the last - known value is \(53\). The missing value \(x=53 + 3\).

Answer:

\(56\)
