To find the next number in the series 16, 11, 13, 8, 10, 5, 7, let’s first analyze the pattern through the series.
The series is formed through a combination of subtracting and then adding numbers alternately:
- From 16 to 11: subtract 5
- From 11 to 13: add 2
- From 13 to 8: subtract 5
- From 8 to 10: add 2
- From 10 to 5: subtract 5
- From 5 to 7: add 2
From the above analysis, we can see an evident pattern:
- The numbers alternate between subtracting 5 and adding 2.
If we follow this pattern, the next step after 7 would involve subtracting 5:
7 – 5 = 2
Therefore, the next number in the series is 2.
