Hello frds..
In this video we have studied the following Examples
Practice set 3.1
1. Which of the following sequences are A.P. ? If they are A.P. find the common
difference .
(1) 2, 4, 6, 8, . . .
(2) 2, 5/2 , 3, 7
3 , . . .
(3) -10, -6, -2, 2, . . .
(4) 0.3, 0.33, .0333, . . .
(5) 0, -4, -8, -12, . . .
(6) - /5 , -1/5 , -1/5 , . . .
(7) 3, 3 + 2 , 3 + 2 2 , 3 + 3 2 , . . .
(8) 127, 132, 137, . . .

2. Write an A.P. whose first term is a and common difference is d in each of the
following.
(1) a = 10, d = 5
(2) a = -3, d = 0
(3) a = -7, d =1/2
(4) a = -1.25, d = 3
(5) a = 6, d = -3
(6) a = -19, d = -4

3. Find the first term and common difference for each of the A.P.
(1) 5, 1, -3, -7, . . .
(2) 0.6, 0.9, 1.2, 1.5, . . .
(3) 127, 135, 143, 151, . . .
(4) 1/4 , 3/4 , 5/4 ,7/4 , . . .
