enter the amount that was subtracted from each term to calculate the next term.

Explanation:

Step1: Analizar la diferencia entre términos

Restamos el segundo término al primer término: $36 - 42 = -6$.

Step2: Verificar con otros términos

Restamos el tercer término al segundo: $30 - 36 = -6$. También, $24 - 30 = -6$ y $18 - 24 = -6$. Esto significa que cada término se obtiene restando 6 al término anterior.

6
