Write an expression to describe the sequence below, and then find the 72nd term. Use n to represent the position of a term in the sequence, where n = 1 for the first term.
78, 79, 80, 81,
The sequence can be described by the expression n + 77.
To find the 72nd term, we substitute n = 72 into the expression:
72 + 77 = 149.
The 72nd term is 149.
The expression to describe the sequence is: 77 + n
To find the 72nd term, substitute n = 72 into the expression:
77 + 72 = 149.
Therefore, the 72nd term in the sequence is 149.
