The first five terms of the sequence are 2 , 0 , -2 , -4 , -6 .
In the question ,
it is given that ,
the first term of sequence is (a) = 2 and
the common ratio is (d) = -2
the general term of the arithmetic sequence is given as
An = a + (n - 1)d
the first term is 2 ,
For second term we put n = 2 ,
A2 = 2 + (2-1)(-2)
= 2 - 2
= 0
For third term , we put n = 3 ,
A3 = 2 + (3-1)(-2)
= 2 + 2*(-2)
= 2 - 4
= -2
For fourth term , we put n = 4 ,
A4 = 2 + (4-1)(-2)
= 2 + 3(-2)
= 2 - 6
= -4
For Fifth term , we put n = 5 ,
A5 = 2 + (5 - 1)(-2)
= 2 + 4(-2)
= 2 - 8
= -6
Therefore , The first five terms of the sequence are 2 , 0 , -2 , -4 , -6 .
The given question is incomplete , the complete question is
If the first term of the sequence is 2 and the common ratio is -2 , write the first five terms of the sequence .
