Question

Find the missing letters by observing the pattern followed by the series:

ab _ bc _ c _ ba _ c.

• A. baac
• B. aabb
• C. caab
• D. aaab

Answer 1

The correct option is C caab

Given sequence is ab_bc_c_ba_c.

By observing the sequence, we can get the pattern as follows:

Make a group of three letters

First group is 'abc'

Now, shift the position of letters on the left by one place, we get the next group as 'bca'

Following in the same manner, we get 'cab' and 'abc' as the next two groups.

Finally we get the series as abc/bca/cab/abc.

Hence the correct option is caab.
