Chapter 11: Q31. (page 581)

Find the indicated term of each arithmetic sequence.
$a_{1} = 3, d = 7, n = 14$

Short Answer

Expert verified

The indicated term of the arithmetic sequence is94.

Step by step solution

Step 1. Given Information.

Given indicated term of arithmetic sequence is $a_{1} = 3, d = 7, n = 14$

Step 2. Calculation.

The n^th term of an arithmetic sequence is given by $a_{n} = a_{1} + (n - 1) d$ .

Here the first term is $a_{1} = 3$

The common difference is $d = 7$

And the required term is $n = 14$

Plugging the values in the formula:

$\begin{array}{l} a_{n} = a_{1} + (n - 1) d \\ a_{14} = 3 + (14 - 1) (7) \\ a_{14} = 3 + (13) (7) \\ a_{14} = 3 + 91 \\ a_{14} = 94 \end{array}$

Step 3. Conclusion.

Hence, the indicated term of the arithmetic sequence is 94.
