Step-by-step explanation:
(x-a)^2=x^2-2ax+a^2
2a=5
a=2.5

The the value of f(n)=
Step-by-step explanation:
The Arithemetic sequence is given as a,a+d,a+2d......a(n-1)d
and f(n)=a(n-1)d
The given sequence is 1/3,4/3,7/3...
By comapring with Arithemetic sequence,
we get a=1/3
a+d=4/3
1/3 + d = 4/3
d=1
To find value of f(10):
take n=10
f(n)=
f(n)=
f(n)=
f(n)=
