An = -2n+4

Please answer.

 

ANSWER :

the sequence is one aritimetic progression , the common difference is -2 , is crescent and the first three terms is 2 , 0 and -2.

STEP BY STEP EXPLANATION :

• The common difference .

A1 = -2(1) + 4 = -2 + 4 = 2

A2 = -2(2) + 4 = -4 + 4 = 0

A3 = -2(3) + 4 = -6 + 4 = -2

___________________________

d = A2 - A1 = 0 - 2 = -2

Therefore , the sequence is one aritimetic progression , the common difference is -2 , is crescent and the first three terms is 2 , 0 and -2.

OK.
