What will be the next term in (120,60,30,15,\ldots)?
Answer and explanation
Correct answer: 7.5
In this sequence, each term is obtained by dividing the previous term by 2: 120 to 60, 60 to 30, and 30 to 15. Therefore, the next term is \(15 \div 2 = 7.5\). Option 8 is not half of 15. Exam tip: Check for a common multiplication or division rule between consecutive terms.
