Question

Which term of the A.P. 52, 48, 44, 40 …..is zero?​

Answer 1

Answer:

Given,the A.P. is–

52,48,44,40....

here, a= 52

d= 48-52

= -4

an= 0

so, n= ?

now,

an= a+(n-1)d

= 0= 52+(n-1)(-4)

= -52= (n-1)(-4)

= (n-1)(-4)= -52

= n-1= (-52)/(-4)

= n-1= 13

n= 13+1

n= 14

so, the 14th term of the A.P. is zero.

Step-by-step explanation:

Formula–

an= a+(n-1)d

where,a= first term

d= common difference
