b3P, c6R, d12T, e24V, ?
Option 1: f48X
Option 2: f46X
Option 3: f48W
Option 4: g48X
Correct Answer: f48X
Solution :
Given:
b3P, c6R, d12T, e24V, ?
In the given series, add 1 to the place value of the lowercase letters, multiply 2 by the numbers and add 2 to the place value of the uppercase letters.
b3P→b + 1 = c, 3 × 2 = 6, P + 2 = R
c6R→c + 1 = d, 6 × 2 = 12, R + 2 = T
d12T→d + 1 = e, 12 × 2 = 24, T + 2 = V
e24V→e + 1 = f, 24 × 2 = 48, V + 2 = X
So, f48X is the missing term of the series. Hence, the first option is correct.
