Arithmetic Progression: Finding the 50th Term
This solution explains how to find the 50th term of the given Arithmetic Progression (AP).
Identify Progression Details
- The sequence provided is an Arithmetic Progression: 3, 8, 13, 18, 23, ........
- The first term ($a$) is 3.
- The common difference ($d$) is found by subtracting any term from its succeeding term:
- $d = 8 - 3 = 5$
- $d = 13 - 8 = 5$
- We need to calculate the 50th term, meaning $n=50$.
Apply Arithmetic Progression Formula
The formula for the $n^{th}$ term ($a_n$) of an Arithmetic Progression is:
$a_n = a + (n-1)d$
Calculate the 50th Term
Substitute the known values ($a=3$, $d=5$, $n=50$) into the formula:
- $a_{50} = 3 + (50-1) \times 5$
- $a_{50} = 3 + (49) \times 5$
- $a_{50} = 3 + 245$
- $a_{50} = 248$
Result
Therefore, the 50th term of the Arithmetic Progression 3, 8, 13, 18, 23, ........ is 248.
