Answer:
180 , 176 , 172.............
let a & d be the first term and and the common difference respectively
a = 180
d = 176 - 180 = -4
a)
Thus yes 0 is the 50th term of the following AP
b)
c) As we know that the very next term after 0 will be -ve thus there are 50 +ve terms in this AP
Answer:
Step-by-step explanation:
an= a+(n-1)d
0=180+(n-1)-4
0=180+-4n+4
0=184+-4n
0-184=-4n
-184=-4n
n=-184/-4=46
0 is the 46th term of this squence
