Q. Write an explicit formula for an, the nth term of the sequence 17,27,37,….Answer: an=
Calculate Common Difference: To find the explicit formula for the nth term of the sequence, we first need to determine the common difference between consecutive terms. We can do this by subtracting the first term from the second term.Calculation: 27−17=10
Find nth Term Formula: The common difference is 10. This means that each term is 10 more than the previous term. Since the first term is 17, the nth term can be found by starting with 17 and adding the common difference (10) multiplied by (n−1) times.Calculation: an=17+10(n−1)
Simplify nth Term Formula: Now we simplify the formula for the nth term.Calculation: an=17+10n−10Calculation: an=10n+7
