anonymous · Answer

you would have to know the formula used to find the nth term in an arithmetic sequence..
$$a_n=a_1+(n-1)d$$

anonymous · Answer

a(n)=the nth term
a(1)=the first term of the sequence
d=common difference

campbell_st · Answer

1st task is to find the common difference d, which can be done using the formula above and the 18th term 

95 = -7 + ( 18  -1 )d

which is 

95 = -7 + 17d

solve for d.

then use the formula above with n = 35

hope this helps.
