Question
Find the common difference of the A.P. and write the next two terms \[0, \frac{1}{4}, \frac{1}{2}, \frac{3}{4}, . . . \]
Solution
In this problem, we are given different A.P. and we need to find the common difference of the A.P., along with the next two terms.
\[0, \frac{1}{4}, \frac{1}{2}, \frac{3}{4}, . . . \]
Here,
a1 = 0
a2 = `1/4`
So, common difference of the A.P. (d) = a2 - a1
`=1/4 -0`
`=1/4`
Also, we need to find the next two terms of A.P., which means we have to find the 5thand 6th term.
So, for fifth term,
`a_5 = a_1 + 4d`
`= 0 + 4(1/4)`
= 1
Similarly, we find the sixth term,
`a_6 = a_1 + 5d`
` = 0 +5(1/4)`
`= 5/4`
Therefore, the common difference is `d = 1/4` and the next two terms of the A.P. are `a_5 = 1,a_6 = 5/4` .
