Fill in the blanks in the following table , given that a is the first term, d the common difference and `a_(n)` the nth term of the A.P:
(i) `a=7, d=3, n=8, a_(n)=?`
(ii) `a= - 18, n=10, a_(n)=0, d=?`
`0= -18+(10-1) d rArr 10d-d=18`
`9d=18 rArr d=(18)/(9)=2`
`d=2`
(iii) `a=? , d= -3, n=18, a_(n)= - 5`
(iv) `a= -18.9, d=2.5, n=?, a_(n)=3.6`
