అందించిన సిరీస్‌లో అనుసరించిన నమూనా:
(√మొదటి పదం - 2)2 = రెండవ పదం

ఇప్పుడు మేము ఇచ్చిన సిరీస్‌లో నమూనాను వర్తింపజేస్తాము:

81 : 49 :: 36 : 16 :: 64 :: ?
(√81 - 2)= 49
(9 - 2)
= 49
(7)= 49
49 = 49

81 : 49 :: 36 : 16 :: 64 :: ?
(√36 - 2)= 16
(6 - 2)
= 16
(4)= 16
16 = 16

81 : 49 :: 36 : 16 :: 64 :: ?
(√64 - 2)= ?
(8 - 2)
= ?
(6)= ?
36 = సమాధానం 

కాబట్టి సరైన సమాధానం ఎంపిక 4)
