Question

Given a first term of 7 and a common difference of -2 give the arithmetic sequence

Answer 1

Answer:

7,5,3,1,-1,-3,-5,-7........ and so on

Answer 2

Answer:

7 , 5 , 3 , 1 , -1 , -3, -5, -7, .....

Step-by-step explanation:

An arithmetic sequence is a sequence that has the property that the difference between any two consecutive terms is a constant. This constant is called the common difference.

If a is the first term of an arithmetic sequence and d is the common difference, the sequence will be:

a, a+d, a+2d, a+3d,.....

Given,

1st term , a= 7

difference, d = -2

So The A.P. will be 7 , 5 , 3 , 1 , -1 , -3, -5, -7, .....
