Consider the Arithmetic Progression: 3, 8, 13, 18, ...... What is the 18th term of the given Arithmetic Progression.

Choose the correct answer from the options given below:

88

The correct answer is Option (2) → 88

To find the 18th term of an Arithmetic Progression (AP), we use the general formula for the $n^{th}$ term:

From the progression 3, 8, 13, 18, ......:

• First term ($a$): 3

• Common difference ($d$): $8-3=5$

• Term to find ($n$): 18

2. Substitute into the formula

$a_{18}​=3+(18−1)×5$

$a_{18}​=3+(17×5)$

$a_{18}​=3+85$

$a_{18}​=88$
