Part 1 #3 Matemática con Tecnología – Obtener términos de una secuencia definida recursivamente El estudiante en cada una de las preguntas debe evaluar la secuencia e ir obteniendo los términos sucesivos en función del anterior o de los anteriores. Pregunta 1: En esta pregunta la secuencia por recurrencia está definida por la fórmula: Donde es un número entero que varía entre y (incluyendo ambos extremos y excluyendo a cero) y son números enteros que varían entre (incluyendo ambos extremos). Al estudiante se le pedirá un término comprendido entre el séptima y quinceava ubicación, la variación de este parámetro implica más trabajo pero no cambia la complejidad de la pregunta. Se eligieron valores enteros porque se pretende que la dificultad del problema no esté en los cálculos (por ejemplo al haber elegido racionales o irracionales) sino en la interpretación correcta de la definición de la secuencia por recurrencia. Dependiendo de los valores de , la secuencia puede ser creciente o decreciente. y que , si alguna de estas condiciones no se cumplen entonces es creciente. o . escriben Pregunta 2
