AMO 2027 Grades 2-3 SET 19 - Self-study Question 6

AMO · AMO 2027 Grades 2-3 SET 19 - Self-study

Question 6

A sequence starts with 3. The second term is 7, the third is 11, the fourth is 15 and the fifth is 19. If you double the 14th number in the pattern, what is the new number?

Self-study rule (editorial): continue adding 4 to get each next term, then double term 14.

Planned review repeat (editorial): this source item appeared in SET 17, Q12. It is one of the 12 final-fill repeats explicitly allocated by the frozen core plan.
