Exercise 1 Page 670

Explicit equations for the nth term of an arithmetic sequence follow a certain format. a_n= a_1+( n-1) d In this form, a_1 is the first term in the sequence, d is the common difference, and n is the position of the desired term in the sequence. We are given that a_1= 14 and d= 9, so we can substitute these values to write the equation. a_n= 14+( n-1) 9 Let's also simplify this equation.

To find the value of the 11th term, we substitute n= 11 into this equation and simplify.

The value of the 11th term in the sequence is 104.
