A letter series is given below in which some letters are missing. Select the option that gives the letters that can fill these blanks in that order.
d_cc_ab_ac_dabd_ccd_b
Answer & explanation
Correct answer: option 3
After dividing the series in 3 parts of 7 letter each we get d_cc_ab / _ac_dab / d_ccd_b. On comparing different positions we get daccdab as a repetitive term.
daccdab / daccdab / daccdab
So the code required for the series is addcaa.
