Question

Find the 13th term of the following A.P , 8,13,18,23..​

Answer 1

Answer:

$\huge\underline{\red{Answer:-}}$

13th term is 68.

Step-by-step explanation:

$\huge\underline{\red{Question:-}}$

$\implies$ Find the 13th term of the following A.P , 8,13,18,23..

$\Large\underline{\green{Hint:-}}$

• We will use the concept of finding the nth term that is $a_n$ = a + (n-1)d

$\Large\underline{\purple{Solution:-}}$

Given, A.P = 8, 13, 18, 23...

Here, a = 8; d = 5 and n = 13

$\implies$ Now,

$\implies$ $a_{n} = a + (n - 1)d$

$\implies$ $a_{13} = 8 + (13 - 1)5$

$\implies$ $a_{13} = 8 + (12)5$

$\implies$ $a_{13} = 8 + 60$

$\implies$ $a_{13} = 68$

Hence, the 13th term of the given A.P is 68.

Answer 2

Answer:

Given, A.P = 8, 13, 18, 23...

Here, a = 8; d = 5 and n = 13

\implies⟹ Now,

\implies⟹ a_{n} = a + (n - 1)da

n

=a+(n−1)d

\implies⟹ a_{13} = 8 + (13 - 1)5a

13

=8+(13−1)5

\implies⟹ a_{13} = 8 + (12)5a

13

=8+(12)5

\implies⟹ a_{13} = 8 + 60a

13

=8+60

\implies⟹ a_{13} = 68a

13

=68

Hence, the 13th term of the given A.P is 68.
