Answer:
Given,
nth term = n+7
Then,
an = n + 7
By replacing n with,
CASE I :
by replacing n with 1 , we get
an = n + 1
=> a1 = 1 + 7
=> a1 = 8
Hence, first term, a1 = 8
CASE II :
by replacing n with 2 , we get
an = n + 7
=> a2 = 2 + 7
=> a2 = 9
Hence, second term, a2 = 9
CASE III :
by replacing n with 3 , we get
an = n + 7
=> a3 = 3 + 7
=> a3 = 10
Hence, third term, a3 = 10
Hence,
First term , a1 = 8
Second term , a2 = 9
Third term , a3 = 10
