Can you crack the logic with which the letters in the attached figure are connected and find the missing letter in the last circle?
If you notice closely, the letters around the center are advancing in accordance with the numerical value of the letter in the center.
In the first picture, the numerical value of A is 1 - F, G, H and I are advancing once.
In the second, numerical value of D is 4 - G, K, O and S are advancing by 4.
Now, F numerical value is 6 and so the letters should advance by 6, which means that the missing alphabet is T.
