Question : Directions: Identify the next letter in the following series.
a d c e b e d f c f e ?
Option 1: h
Option 2: g
Option 3: f
Option 4: d
Correct Answer: g
Solution :
Given:
a d c e b e d f c f e ?
Divide the series into 3 parts → a d c e / b e d f / c f e ?
Now, add 1 to each letter of the first part to obtain the second part –
adce→a + 1 = b; d + 1 = e; c + 1 = d; e + 1 = f→bedf
Similarly, add 1 to the second part to obtain the third part –
bedf→b + 1 = c; e + 1 = f; d + 1 = e; f + 1 = g→cfeg
So, g is the missing letter in the series. Hence, the second option is correct.
