Read Solution (Total 13)

FIRST of I SAY that above it is given it is a SERIES so 3054 is not correct.

then solution is:-

DIFFERENCE BET first two term=1030-518=512=8^3.

then 1130-1030=100=10^2

then 2858-1130=1728=12^3

then 3054-2858=196=14^2

BUT 7160-2054=4106!=16^3(4096)

then if 7474-4096=324=18^2

So answer is 7160.
