Find the missing term X with proper explanation.

Answer 1

the terms of the given series are (2^3-1), (3^3-1), (4^3-1), (5^3-1)
therefore,
the missing term = (8^3-1)=(512-1) = 511

hope it helps... :)

Answer 2

Hiii friend,

(1) 7

= (2)³-1

= 8-1 = 7

(2) 26

= (3)³ -1

= 27 -1 = 26

(3) 63

= (4)³ - 1

= 64 - 1 = 63

(4) 124

= (5)³ - 1

= 125 - 1 = 124

(5) 215

= (6)³ - 1

= 216 - 1

= 215

Therefore,

(6) X

= (8)³-1 = 512-1 = 511

HOPE IT WILL HELP YOU.... :-)
