If the first term of an arithmetic progression is (7) and the common difference is (2), what is the second term?
Answer and explanation
Correct answer: 9
In an arithmetic progression, the next term is found by adding the common difference to the preceding term. Thus, second term = first term + common difference = 7 + 2 = 9. Option 8 would result from adding 1, not the given common difference 2. Exam tip: use the formula \(a_2=a_1+d\) for the second term.
