Question
For the following A.P.s, write the first term a and the common difference d: `(1)/(3), (5)/(3),(9)/(3),(13)/(3)`,...
Solution
`(1)/(3), (5)/(3),(9)/(3),(13)/(3)`,...
Here first common term (a) = `(1)/(3)`
and common difference (d) =
`(5)/(3) - (1)/(3) = (4)/(3), (9)/(3) - (5)/(3) = (4)/(3)`,...
= `(4)/(3)`.
