Question

by using this pattern evaluate
a)7^3

Answer 1

hey, 7³=43+45+47+49+51+53+55=343

Answer 2

Answer:

The value of 7³ is 343.

Step-by-step explanation:

From the given pattern it is noticed that the cube of numbers is defined as the sum of next consecutive odd integers.

$1^3=1$

$2^3=8=3+5$

$3^3=27=7+9+11$

$4^3=64=13+15+17+19$

$5^3=125=21+23+25+27+29$

$6^3=216=31+33+35+37+39+41$

$7^3=343=43+45+47+49+51+53+55$

Therefore the value of 7³ is 343.
