U can find Its first term by putting n= 1
i.e.
15-7=8
2nd term =15-14=1
Hence Common difference is 2nd term-1st term
1-8=> -7
Got ittt

a(n)=15-17n
a(1)=15-17=-2
a(2)=15-34=-19
a(3)=15-51=-36
d=a(2)-a(1)=-19-(-2)=-19+2=-17
=a(3)-a(2)=-36-(-19)=-36+19=-17
d=-17
a(1)=15-17=-2
a(2)=15-34=-19
a(3)=15-51=-36
d=a(2)-a(1)=-19-(-2)=-19+2=-17
=a(3)-a(2)=-36-(-19)=-36+19=-17
d=-17
