Instructions
In each of the following letter series, some of the letters are missing which are given in that order as one of the alternatives below it. Choose the correct alternative.
Solution
We start the series with a,b,c as the first 3 terms.
For the next 3 terms, we start with the last term i.e 'c' of the previous series(a,b,c in his case), and continue with the next 2 terms in circular fashion (a,b,c,a,b,c). So the second set of 3 terms comes out as c,a,b.
Continuing in a similar way, the next 3 terms are b,c,a, and the subsequent terms are a,b,c.
Hence, the final series turns out as a,b,c,c,a,b,b,c,a,a,b,c.
