An arithmetic sequence (a_n) is as follows:
where 
is the first term and d is the constant difference,
thus, we see that the n'th term of an arithmetic sequence is
in our particular case d=5, the third term is 8, so we have:
and the general term is
,
Answer: first term is -2, n'th term is -2+5(n-1)

The value B is 7. If we apply B=7 the answer is 17 for the expression 17×
Step-by-step explanation:
The given expression is 17×
Step:1
Form an equation from given data,
17×= 17..............................(1)
(∵ product equal to 17)
Step:2
Check for alternatives by apply the value of B in eqn (1)
Assume be value of B for check the equation
B=1
Equation becomes,
17× = 2.4286 ≠ 17
Take, B=2,
17× = 4.8571 ≠ 17
Take, B=3,
17× = 7.2857 ≠ 17
similarly,
B=7,
17× = 17 (∵ The product equals to 17)
Result:
So, the answer for B is 7.
