Solution & Step-by-step Explanation
Let's look at the pattern matching the first letters of each cluster:
E(5)
+12
Q(17)
+12
C(3 or 29)
+12
O(15)
Let's check the second letter of each cluster:
I(9)
+12
U(21)
+12
G(7 or 33)
+12
S(19)
Let's check the third letter of each cluster:
L(12)
+12
X(24)
+12
J(10 or 36)
+12
V(22)
Combining these letters gives the cluster OSV.
