Some were awarded a mark for 4n in their answer. More often, the 4 was a constant term in answers such as n = 4. A few gave the term-to-term rule, add 4. A small number thought this was a quadratic sequence.
— Examiner report, May/June 2025, 0607/13 Q4(b) (Cambridge)
For one method, the answer to part (a) was needed as well as the product of prime numbers for 24, then the prime factors that make up the LCM can be seen; if the answer was given as a product of primes, 23 3 5 , this was awarded one mark. Another, more popular method was to list the multiples of 60 and 24 to see what number is first to appear in both lists. There was a mark available for a higher...
