Question

which term
of the ap
Ap 120, 116,112 is nagative
term​

Answer 1

Step-by-step explanation:

From the given AP a=120 and d=116-120= -4

Now let nth term of the AP be 0

Then a+(n-1)d=0

Or 120+(n-1)(-4)=0

Or 120-4n+4=0

Or 124=4n

So n=124/4=31

So the 31th term of given AP is 0 but the common difference is negetive.

So the term after after zero will be the first negetive term i.e. 32th term will be first negetive term
