Solution & Step-by-step Explanation
Let us observe the relationship between consecutive letter blocks:
Each block consists of three consecutive alphabets in reverse order:
V→U→T
O→N→M
G→F→E
Let us track the first letters of each triad to establish the step difference:
V(22)
−7
O(15)
O(15)
−8
G(7)
Following a pattern of shifting positions, let's look at the gap between the last letter of one group and the first letter of the next group:
From T(20) to O(15) is −5.
From M(13) to G(7) is −6.
From E(5) to the next first letter should be −7⟹5−7=−2≡24→X.
The group starting with X in reverse order is X→W→V.
Therefore, the missing group is XWV.
