Explanation
The difference of the two consecutive numbers are 1, 4, 9, 16, 25, 35.
This is clearly , $$+1^2, +2^2, +3^2, +4^2, +5^2, +6^2$$
Here 35 is wrong, So our wrong number is 91
Given series follows Cubes on Prime Numbers i.e $$2^3, 3^3, 5^3, 7^3, 11^3$$ but $$11^3$$ is 1331.
so 1381 is wrong
The given sequence a combination of two series:I)Z, W, T, Q, ? and II)S, O, K, G, ?
