What is the value of (d) in the sequence (31,27,23,19,\ldots)?

Answer and explanation

Correct answer: -4

In an arithmetic progression, the common difference is d = second term − first term. Here, d = 27 − 31 = -4. Each successive term is 4 less than the preceding term, so the common difference is negative. Although 4 is the magnitude of the decrease, it is not the common difference. Exam tip: always subtract an earlier term from the next consecutive term to find d.
