If (x, x+7, x+14,\ldots) is an arithmetic progression, what is the difference between the second and first terms?

Answer and explanation

Correct answer: 7

The first term is x and the second term is x+7. Thus, second term − first term = (x+7)-x=7. Therefore, the common difference is 7. Note that x+7 is the second term, not the difference. Exam tip: To find the common difference of an AP, subtract a term from the term immediately after it.
