Question

type the missing number in this sequence:
□, 74, 79, 84, 89

Explanation:

Step1: Find the common difference

Check the difference between consecutive terms: \(79 - 74 = 5\), \(84 - 79 = 5\), \(89 - 84 = 5\). So the common difference \(d = 5\).

Step2: Find the missing term

To find the term before 74, subtract the common difference from 74: \(74 - 5 = 69\).

Answer:

69
