letter or alphabet series Detailed Explanation And More Example

Answer: (a)

We have 3 patterns :

I. ABCD ….. XYZ, which occurs only once.

II. YX ….. BA, which repeats alternately.

III. BC ….. YZ, which repeats alternately.

Now, I has 26 terms.

So, number of terms before the desired term = (999 - 26) = 973.

Each of the patterns which occurs after

I, has 25 letters. Now, 973 + 25 gives quotient = 38 and remainder = 23.

Thus, the 1000th term of the given series is the 24th term of the 39th pattern after I.

Clearly, the 39th pattern is II and its 24th term is B.
