How much equal increase is there in the sequence (25,30,35,40,\ldots)?
Answer and explanation
Correct answer: 5
To find the equal increase, subtract each term from the term immediately after it: \(30-25=5\) and \(35-30=5\). Therefore, the common difference of this sequence is \(d=5\). Option 10 is incorrect because it is not the difference between consecutive terms. Exam tip: In an AP, use \(d=a_{n+1}-a_n\).
