Logical Reasoning - Letter and Symbol Series - Discussion

Discussion :: Letter and Symbol Series - Type 1 (Q.No.3)

In these series, you will be looking at both the letter pattern and the number pattern. Fill the blank in the middle of the series or end of the series.


FAG, GAF, HAI, IAH, ____

[A]. JAK
[B]. HAL
[C]. HAK
[D]. JAI

Answer: Option A


The middle letters are static, so concentrate on the first and third letters. The series involves an alphabetical order with a reversal of the letters. The first letters are in alphabetical order: F, G, H, I , J. The second and fourth segments are reversals of the first and third segments. The missing segment begins with a new letter.

How can we get last letter ?

Follow the alphabetical order

A B C D E F G H I J K L M N............

The middle letter A is static
Now the 1st and 3rd letter is changing

1st FAG
2nd GAF(change the position of the letter F and G)
3rd HAI
4th IAH(change the position of the letter H and I)
5th JAK

How to get this answer?

Letter A is in middle of each word F G change their position as per the alphabetical order after G comes H and I so same things happen and after I comes J and K so the answer is JAK. Hope you guys understand!

Here we give the alphabetical order.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

Y Z.
25 26.

Here the given terms is FAG = 617,
GAF = 716.
Here we used the G so we go sequentially for unused,
FAG = 617.
HAI =819.

IAH = 918 SO another word is,
JAK = 10111.

First letters are......f, g, h, i. So next comes `j`.

Second letters are......a, a, a, a. So next letter also comes `a`.

Third letters are.......g, f, i, h. So here is reverse of f, g and i, h so next letter is reverse of j, k.

So answer : jak.

This is very simple :).

First Letters sequential = F, G, H, I.

Second Letter is a static (not changing) letter = A.

Here's the game! Let's assume you are counting backwards //"started Z all the way to A"// when you get to.

gf (reversed) = fg.

ih (reversed) = hi.

kj (reversed) = Jk.

Therefore the answer is: JAK.

Hopefully I put a smile on your face :-).

The third letter of first word is alphabetical order to the third letter of third word.

Really, I'm not getting that why JAK is there? Why not JAI?

HARIHARAN.B said: (Nov 10, 2016)  
FAG : 6 1 7
GAF : 7 1 6
HAI : 8 1 9
IAH : 9 1 8
JAK : 10 1 11

Explain clearly?

KRISHNA said: (Aug 29, 2017)  
Here everyone has a problem with K(of JAK).

G of FAG comes from GAF(1st ltr of this) and similarly HAI and IAH related.
So, K of JAK comes from KAJ(which will be the next element).

Adwitiya Biswas said: (Jul 12, 2018)  
Please explain, why the last letter is K here?

John said: (Jul 18, 2018)  
1st letters FGHI ... NEXT ..J.
2nd letter A constant.
3rd letter which is opposite to J is K because,
In FAG F, G are opposite like that.

Please explain in details.

Jerry said: (Nov 19, 2018)  
Nice explanation @Preetha.

Sukdev Gorai said: (Oct 13, 2019)  
Last letter "k" why?

ASIF said: (Oct 21, 2019)  
H opposite word I why do not JIA.

Rishav Kumar said: (Jul 19, 2020)  
2nd letter is static -> A.
1st letter is consecutive
3 Letters goes like;
G ~ F -1 (according to number values of alphabets).
F ~ I. +3 (according to number values of alphabets).
I ~. H. -1.
We see that the series of -1 and +3 is going consecutively.

H+3 = K.
Our final answer is;
