¡Hola!

Explicación paso a paso:

Primera fila

$2n = \\ 2 \times 5 = 10$

$n + (n - 1) = \\ 5 + (5 - 1) = \\ 5 + 4 = 9$

$(n - 1) + (n - 1) + 1 = \\( 5 - 1) + (5 - 1) + 1 = \\ 4 + 4 + 1 = 9$

$2(n - 1) + 1 = \\ 2(5 - 1) + 1 = \\ 10 - 2 + 1 = 9$

$2n - 1 = \\ 2 \times 5 - 1 = \\ 10 - 1 = 9$

Segunda fila:

$2n = \\ 2 \times 8 = 16$

$n + (n - 1) = \\ 8 + (8 - 1) = \\ 8 + 7 = 15$

$(n - 1) + (n - 1) + 1 = \\ (8 - 1) + (8 - 1) + 1 = \\ 7 + 7 + 1 = 15$

$2(n - 1) + 1 = \\ 2(8 - 1) + 1 = \\ 16 - 2 + 1 = 15$

$2n - 1 = \\ 2 \times 8 - 1 = \\ 16 - 1 = 15$

Tercera fila:

$2n = \\ 2 \times 12 = 24$

$n + (n - 1) = \\ 12 + (12 - 1) = \\ 12 + 11 = 23$

$(n - 1) + (n - 1) + 1 = \\ (12 - 1) + (12 - 1) + 1 = \\ 11 + 11 + 1 = 23$

$2(n - 1) + 1 = \\ 2 (12 - 1) + 1 = \\ 24 - 2 + 1 = 23$

$2n - 1 = \\ 2 \times 12 - 1 = \\ 24 - 1 = 23$
