Event B has taken place every 3 years.

Work out the last year, before 2019, when both events took place. [2 marks]
| Answer | Mark | Comments |
|---|---|---|
| 2015 2011 2007 or 2016 2013 2010 (2007) or \(4 \times 3\) or 12 (years) | M1 | 12 is implied by an answer \(2019 - 12n\) or \(2019 + 12n\) where \(n\) is a positive integer |
| 2007 | A1 | accept 07 |
Additional guidance
| Allow the years to be written with two digits for M1 eg 15 11 (0)7 | |
| 15 11 (0)7 Answer 07 | M1A1 |
| 15 11 (0)7 Answer 7 | M1A0 |
| Answer 7 without M1 awarded | M0A0 |
| Answer 1995 or 1983 or 2031 or 2043 | M1A0 |
| Ignore any errors in a list after 2007 eg 2015 2011 2007 2004 | M1 |
| Ignore any errors in a list after 2010 eg 2016 2013 2010 2006 | M1 |
