Question

Write an expression to describe the sequence below. Use n to represent the position of a term in the sequence, where n = 1 for the first term.

78, 156, 234, 312,.

Answer 1

The sequence can be described by the expression 78 + 78(n - 1), where n represents the position of a term.

Step-by-step explanation:

The sequence can be described by the expression 78 + 78(n - 1), where n represents the position of a term in the sequence.

For example, the first term (n = 1) is 78 + 78(1 - 1) = 78, the second term (n = 2) is 78 + 78(2 - 1) = 156, and so on.

This expression represents the pattern of adding 78 to each previous term to get the next term in the sequence.
