Question

Pls help me with this question. Would appreciate step by step explanation.​

Answer 1

`\sf\\V_1=2^3\\\textsf{or, }V_1=2^3(1)\\\\V_2=2^3+4^3\\\textsf{or, }V_2=2^3+(2*2)^3=2^3+2^3.2^3\\\textsf{or, }V_2=2^3(1^3+2^3)`

`\sf\\V_3=2^3+4^3+6^3\\\textsf{or, }V_3=2^3.1^3+2^3.2^3+2^3.3^3\\\textsf{or, }V_3=2^3(1^3+2^3+3^3)`

`\sf\\\textsf{So the nth term will be given by: }\\\\V_n=2^3*(1)/(4)n^2(n+1)^2\\\\\textsf{or, }V_n=2n^2(n+1)^2`
