Question : Directions: Select the letter cluster that can replace the question mark (?) in the given letter cluster series.
AZA, EVW, ?, OLM, UFG
Option 1: JRS
Option 2: IRS
Option 3: JQS
Option 4: IRV
Correct Answer: IRS
Solution :
Given:
AZA, EVW, ?, OLM, UFG
Write the vowels at the first place of each term and then the second letter is the opposite of the first letter and add 1 to the place value of the second letter to obtain the third letter of the previous term to obtain the next term in the series –
AZA
→
A and Z are opposite pairs; Z + 1 = A
EVW
→
E and V are opposite pairs; V + 1 = W
IRS
→
I and R are opposite pairs; R + 1 = S
OLM
→
O and L are opposite pairs; L + 1 = M
UFG
→
U and F are opposite pairs; F + 1 = G
So, IRS is the missing term in the series. Hence, the second option is correct.
