Question
Write first four terms of the A.P. when the first term a and the common differenced are given as follows:
a = 4, d = -3
Solution
a = 4, d = -3
Let the series be a1, a2, a3, a4 …
a1 = a = 4
a2 = a1 + d = 4 - 3 = 1
a3 = a2 + d = 1 - 3 = -2
a4 = a3 + d = -2 - 3 = -5
Therefore, the series will be 4, 1, -2 -5…
First four terms of this A.P. will be 4, 1, -2 and -5.

Which term of following A.P. is −940.
50, 40, 30, 20 ........
Activity :- Here a = `square`, d = `square`, tn = −940
According to formula, tn = a + (n − 1)d
−940 = `square`
n = `square`
Common difference, d = ? for the given A.P., 7, 14, 21, 28 ........
Activity :- Here t1 = 7, t2 = 14, t3 = 21, t4 = `square`
t2 − t1 = `square`
t3 – t2 = 7
t4 – t3 = `square`
Therefore, common difference d = `square`
