Question

find weather zero is the term of Ap 40,37,34,31.....

Answer 1

a=40
d=(37-40)=(-3)
an=0

an=a+(n-1)d
0=40+(n-1)(-3)
0=40+3n+3
3n=43
n=14.3
since value of n is decimal, therefore 0 is not a term of the given ap

Answer 2

Heya !!!





AP = 40 , 37 , 34 , 31 .....



Here,


First term (A) = 40


Common Difference (D) = 37-40 = -3




Let The nth term of the given ap be 0. Then



Tn = 0



A + ( N -1) × D = 0



40 + ( N -1) × -3 = 0



40 - 3N + 3 = 0



43 - 3N = 0


-3N = -43


N = 43/3




Number of terms can't be a fraction.




Therefore,



0 is not a term of the given AP.
