In the sequence d_n = 5 - 4n, what is the variable that determines the position in the sequence?

Jun 8, 2022 ... In this paper we seek to investigate how visual programming could change or contribute to the teaching and learning of variables in early algebra. A variable is a letter that represents a number or quantity whose value may change. A constant is a number whose value always stays the same. To create a symbolic number in a symbolic expression, use sym . Do not use syms to create a symbolic expression that is a constant.
