Q. 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.25,26,27,28,…_____
Identify pattern: To find the expression for the sequence, we start by identifying the pattern. The sequence is increasing by 1 each time. So, the common difference is 1.
Write nth term expression: Since the first term when n=1 is 25, we can write the nth term as the first term plus the common difference times (n−1). So, the expression is 25+(n−1)×1.
Simplify expression: Simplify the expression to get the final form. 25+(n−1)×1 simplifies to 25+n−1.
Combine like terms: Further simplifying, we combine like terms to get the final expression: 24+n.
