If (a=4) and (d=6), what are the first three terms of the arithmetic progression?
Answer and explanation
Correct answer: (4, 10, 16)
The first term is a=4 and the common difference is d=6. Therefore, the terms are 4, 4+6=10, and 10+6=16, so the first three terms are (4, 10, 16). Option A is incorrect because it adds 4 instead of the common difference 6. Exam tip: Add the common difference to each term to obtain the next term.
