Week 281 (20th January 2023)

Emily has nearly finished her maths homework but is struggling with the last question on sequences. 
 
What comes next in the following sequence:
 
1561    4413    2120    1089    6847    2604    8362   ? 
 
Can you help Emily find the next number in the sequence? 

Answer:   

The sequence is based on the 12 times table in reverse (ie 156, 144, 132, 120 etc)     

So, the last numbers of the sequence would be the first three terms of the 12 times table (ie 24, 12 and 0).   

The number “2” from 24 has been accounted for in the number 8362. 

Therefore, the last number of the sequence would be 4120 (being 24, 12 and 0).
