Descubre la secuencia que acaba en 3

by Juana Socorro Garcia Ureña
1

Definición

Una secuencia de números que termina en 3 es aquella en la que cada término tiene el dígito final igual a 3. Ejemplos típicos aparecen al sumar 10 en cada paso.

2

Primera parte

El dígito final de cada número es 3. Por lo tanto, todos los términos terminan con el dígito 3 y comparten esa característica al revelar su unidad.

3

Forma de la secuencia

La secuencia puede expresarse como a_n = 10n + 3, donde n = 0, 1, 2, ... . Cada paso suma 10 al anterior.

4

Ejemplos iniciales

3, 13, 23, 33, 43, 53, 63, 73, 83, 93 son términos de la secuencia que termina en 3.

5

Propiedad clave

Todos los números de la secuencia comparten que su unidad es 3. No importan las decenas, centenas u otras cifras.

6

Cómo identificarlos

Para saber si un número termina en 3, revisa la unidad. Si es 3, pertenece a la secuencia.

7

Práctica rápida

¿Qué número de la serie cumple terminar en 3 y es mayor que 53? Pista: añade 10 al último término conocido.

8

Números en 0–100

En el rango de 0 a 100, los términos son: 3, 13, 23, 33, 43, 53, 63, 73, 83, 93.

9

Propiedades matemáticas

Las congruencias mod 10 resultan en n ≡ 3 (mod 10), lo que explica por qué todos terminan en 3.

10

Desafío final

Construye la lista hasta 10 términos más allá de 93 y verifica que cada término termina en 3 al sumarle 10.
