Question : Directions: A series is given, with one term missing. Choose the correct alternative from the given ones that will complete the series.
ZbYa, XdWc, VfUe, ?
Option 1: TgSh
Option 2: ThSg
Option 3: ThSi
Option 4: ShTg
Correct Answer: ThSg
Solution :
Given:
ZbYa, XdWc, VfUe, ?
In the given series, subtract and add 2 alternately to the place value of the letters of the previous term to obtain the next term –
ZbYa→Z – 2 = X; b + 2 = d; Y – 2 = W; a + 2 = c
XdWc→X – 2 = V; d + 2 = f; W – 2 = U; c + 2 = e
VfUe→V – 2 = T; f + 2 = h; U – 2 = S;
e + 2 = g
So, ThSg is the missing term in the series. Hence, the second option is correct.
