Answer 1

Answer:

hiiiiiii............Good after noon

Answer 2

Answer:

8

Step-by-step explanation:

Given,common difference(d)=-2,number of terms(n)=5 and the nth term(an)=0

To Prove-the value of a

Proof-we know that the nth term of an arithematic progression can be written as

$a_n$=a+(n-1)d

0=a+(5-1)(-2)

0=a+4(-2)

0=a-8

a=8

hence proved...... hope this helps... :D
