if the common difference in an article is -3 and the first term is 7 what is the 14th term?

a)-32
b)-35
c)-49
b)87 !

I got A, -32, but it has been awhile since I have learned this in my math class. You might want to wait for someone else to verify this answer. 

Common differnce
an=a1+d(n-1)
d=common difference
a1=first term
so

given

common difernce is -3 and first term is 7
an=7-3(n-1)
14th term
a14=7-3(14-1)
a14=7-3(13)
a14=7-39
a14=-32

the 14th term is -32
A is answer
