Answer 1

Respuesta:

solución

Explicación paso a paso:

1

$s = \frac{16 \times (16 + 1) \times (2 \times 16 + 1)}{6}$

$s = 1496$

2

$s = \frac{25 \times (25 + 1) \times (2 \times 25 + 1) }{6}$

$s = 5525$

3.

$s = \frac{13 \times (13 + 1) \times (2 \times 13 + 1)}{6} - \frac{(6 \times (6 + 1) \times (2 \times 6 + 1)}{6}$

$s = 728$

4.

$s = \frac{(1 + 1999) \times 1999}{2}$

$s = 1999000$

5.

$s = \frac{(1 + 25) \times 25}{2} + \frac{(10 + 50) \times 41}{2}$

$s = 1555$

6.

$s = ( \frac{10 \times (10 + 1)}{2}) ^{2}$

$s = 3025$
