The n-th term is

U_n = \dfrac14 n^2 (n+1)^2

so the 39th term is

U_{39} = \dfrac14 39^2 40^2 = \boxed{608,400}

Observe that

2^3 + 4^3 + 6^3 = 2^3 + 2^3\times2^3 + 2^3\times3^3 = 8\left(1^3+2^3+3^3)

which suggests that

V_n = 8U_n = \boxed{2n^2(n+1)^2}

Answer:

  72 +13n = 163

  7 nights

Step-by-step explanation:

At 13 pages per night, Mario will read 13n pages in n nights. That plus the pages already read will total 163:

  equation: 13n +72 = 163

__

To solve this, we can subtract 72, then divide by the coefficient of n.

  13n = 91 . . . . . . subtract 72 from both sides

  n = 7 . . . . . . . . divide both sides by n

Mario read 7 nights.
