Solution
The correct option is AG4K13O41 Let's identify the pattern in the formula.
The first letter of the formula follows a pattern of +3. A(1)(+3)−−→D(4)(+3)−−→G(7)(+3)−−→J(10)
The first letter of the missing element is J.
Similarly, the other letters also follow the same pattern. E(5)(+3)−−→H(8)(+3)−−→K(11)(+3)−−→N(14)
The second letter of the missing element is K.
And for the third letter: I(9)(+3)−−→L(12)(+3)−−→O(15)(+3)−−→R(18)
The third letter of the missing element is O.
Now, let's identify the numbers in the subscript.
The numbers follow the pattern: (×3+1), (×3+2) 2×3+1=7 7×3+2=23
The next number is starting from 3. 3×3+1=10 10×3+2=32
The next number should start from 4. 4×3+1=13 13×3+2=41
Hence, this is the number series the missing formula follows.
Let's see the last one.
The next number should start from 5.
5 × 3 + 1= 16
16 × 3 + 2 = 50
