Explanation:
The n-th term of an A.P. is given by the expression,
an=a+(n-1)d
Where a is the first term and d is the common difference.
We have to find the first four terms of the A.P. which has a=4,d=-3.
a 1 = a = 4 a 2 = a + d = 4 + ( 3 ) = 1 a 3 = a + 2 d = 4 + 2 ( 3 ) = 2 a 4 = a + 3 d = 4 + 3 ( 3 ) = 5
Therefore, the first four terms of the given A.P. are 4,1,-2,-5.
