The number which best completes the sequence below is: 1, 1, 3, 2, 4, 6, 5, 25,…?
Solution:
Given sequence 1, 1, 3, 2, 4, 6, 5, 25,…
We can write the given sequence as 1, 12, 3, 2, 22, 6, 5, 52
The third term is ‘2’ added to the first term
Similarly, the 6th term is ‘2’ added to the 4th term
We can also see a pattern between the 4th term and 5th term and also between the 6th term and 7th term, the difference is the same ‘-1’
Hence, the pattern is ‘squared’ then ‘ added 2 to that square ‘ and
then ‘subtracted 1 from the previous term’
So, we need to add 2 to 52, we get next term as 25 + 2 = 27
Hence, the number 27 best completes the sequence
The number which best completes the sequence below is: 1, 1, 3, 2, 4, 6, 5, 25,…?
Summary:
The number 27 completes the sequence 1, 1, 3, 2, 4, 6, 5, 25,…
