Answer 2

Answer:

The 6th term of an A.P is given by

a6=a1+(6−1)d

a6=a1+(5)d)

and given 6th term is (a6=12)

12=a1+(5)d......eq(1)

8th term of an A.P is given by

a8=a1+(8−1)d

a8=a1+(7)d

and given 8th term is (a8=22)

22=a1+(7)d......eq(2)

substract eq(1) by eq(2) we get

22−12=a1−a1+(7−5)d

⟹10=2d

⟹d=5  common difference of A.P

now put d=5in eq(1) we get

12=a1+(5)×5

12=a1+25

a1=12−
