Question : Directions: In the following question, the number of letters skipped in between adjacent letters in the series increased by one. Which of the following series observe the rule?
Option 1: KILMOPQ
Option 2: NOPRQST
Option 3: BEINTAI
Option 4: CDEHGFI
Correct Answer: BEINTAI
Solution : Let's check the options –
First option:
KILMOPQ; K – 2 = I; I + 3 = L; L + 1 = M; M + 2 = O; O + 1 = P; P + 1 = Q
Second option:
NOPRQST;
N + 1 = O; O + 1 = P; P + 2 = R; R – 1 = Q; Q + 2 = S; S + 1= T
Third option:
BEINTAI; B + 3 = E; E + 4 = I; I + 5 = N; N + 6 = T; T + 7 = A; A + 8 = I
Fourth option:
CDEHGFI;
C + 1 = D; D + 1 = E; E + 3 = H; H – 1 = G; G – 1 = F; F + 3 = I
So, the third option is different from the other three options because the difference in the position value of the letters is consecutive natural numbers. Hence, the third option is correct.
