Question : Directions: In the following question, a series is given with one or more term(s) missing. Choose the correct alternative from the given options. az225, cx423, ev621, _?, _?
Option 1: jq1116, kp1215
Option 2: go1314, mn126
Option 3: gt819, ir1017
Option 4: gu720, gt819
Correct Answer: gt819, ir1017
Solution : Given: az225, cx423, ev621, _?, _ ?
az225→a + 2 = c; a and z are opposite pairs; 225 + 198 = 423 cx423→c + 2 = e; c and x are opposite pairs; 423 + 198 = 621 ev621→e + 2 = g; e and v are opposite pairs; 621 + 198 = 819 gt819→g + 2 = i; g and t are opposite pairs; 819 + 198 = 1017
So, gt819 and ir1017 are the missing terms of the series. Hence, the third option is correct.
