Answer:
4.5
Step-by-step explanation:
Given,
a = 4.5
d = 0
n = 101
To find : an = ?
Formula : -
an = a + ( n - 1 ) d
= 4.5 + ( 101 - 1 ) 0
= 4.5 + 0
an = 4.5

➤ What is A.P ?
★ Given:-
[tex]\sf{n = 101}[/tex]
★ To find:
[tex]\sf{a_n}[/tex]
★ Solution:-
Formula we are going to use :
[tex]\sf{a_n = a+(n-1)d}[/tex]
Where,
" n " = number of terms
" a " = First term of the A.P.
" d " = Common Difference
We will simply substitute the values in it.
We know,
In an A.P.
[tex]\sf{a_n = a + (n-1)d}[/tex]
Therefore,
= [tex]\sf{a_n = 4.5 + (101 - 1)\times0}[/tex]
= [tex]\sf{a_n = 4.5 + 100\times0}[/tex]
= [tex]\sf{a_n = 4.5}[/tex]
Hence,
[tex]\sf{a_n = 4.5}[/tex]
