Question

which term of the ap 8,-4,-16,-88 is -880​

Answer 1

Answer:

let -880 be nth term

nth term = a + (n-1)d

=>-880=8+(n-1)(-12)

=>-880=8-12n+12

=>880=12n-20

=>12n=900

=>n=75

so, 75th term of the series is -880

Answer 2

Step-by-step explanation:

Given:

AP: 8,-4,-16

AP: 8,-4,-16=>=8 , d= -12 , an= -880

an = a+(n-1)d

-880 = 8+(n-1) -12

-880 -8= -12n +12

-888-12 =-12n

-900= -12n

n= -900/-12= 75

Therefore the 75th term of the AP is -880
