Select the letter cluster which does not belong to the

Solution

The pattern followed here is: The 2nd letter is obtained by adding 3 to the place value of the 1st letter, and the 3rd letter is obtained by adding 3 to the place value of the 2nd letter. ADG: A [Place value of A is 1, (1 + 3) = 4 = D] D [Place value of D is 4, (4 + 3) = 7 = G] FIL: F [Place value of F is 6, (6 + 3) = 9 = I] I [Place value of I is 9, (9 + 3) = 12 = L] LOR: L [Place value of L is 12, (12 + 3) = 15 = O] O [Place value of O is 15, (15 + 3) = 18 = R] SVZ: S [Place value of S is 19, (19 + 3) = 22 = V] V [Place value of V is 22, (22 + 4) = 26 = Z] In 'SVZ', the difference between the 2nd and 3rd letter is 4, whereas in all other options, it is 3.
