Chapter 12: Q. 263 (page 1218)

In the following exercises, write the first five terms of each arithmetic sequence with the given first term and common difference.
$a_{1} = 5$ and $d = 3$

Short Answer

Expert verified

We get the first five terms of the sequence as following:

$5, 8, 11, 14, 17$

Step by step solution

Step 1. Given information

We have first term $a_{1} = 5$ and common difference $d = 3$ .

We have to write the first five terms of this arithmetic sequence.

Step 2. Find the second term

First term is $5$ .

Formula for $n^{t h}$ term is $a_{n} = a_{1} + (n - 1) d$ .

Put $n = 2$ .

$a_{2} = a_{1} + (2 - 1) 3 a_{2} = 5 + (1) 3 a_{2} = 5 + 3 a_{2} = 8$

Step 3. Find third term

Put $n = 3$

$a_{3} = a_{1} + (3 - 1) 3 a_{3} = 5 + (2) 3 a_{3} = 5 + 6 a_{3} = 11$

Step 4. Find fourth term

Put $n = 4$ .

$a_{4} = a_{1} + (4 - 1) 3 a_{4} = 5 + (3) 3 a_{4} = 5 + 9 a_{4} = 14$

Step 5. Find fifth term

Put $n = 5$ .

$a_{5} = a_{1} + (5 - 1) 3 a_{5} = 5 + (4) 3 a_{5} = 5 + 12 a_{5} = 17$
