Select the option that is related to the fifth alphanumeric-cluster in the same way as the second alphanumeric-cluster is related to the first alphanumeric-cluster and the fourth alphanumeric-cluster is related to the third alphanumeric-cluster.
P4 : N9 :: M16 : K25 :: G49 : ?
P4 : N9
P4 ==>Â P $$2^2$$ ==>Â (P-2) $$(2+1)^2$$Â ==> N $$3^2$$Â ==> N9
M16 : K25
M16 ==>Â M $$4^2$$ ==>Â (M-2) $$(4+1)^2$$Â ==> K $$5^2$$ ==> K25
G49 : ?
G49 ==>Â G $$7^2$$ ==>Â (G-2) $$(7+1)^2$$Â ==> E $$8^2$$Â ==> E64
Hence 'E64' will come in place of the question mark.
