Question

which term of the a.p 2,-1.-4 is -77/

Answer 1

a=2

d=-3

so, using An = a + (n-1)d

-77=2+(n-1)*-3

-79=(n-1)*-3

maybe ur question is incomplete or some values are wrong

u can solve easily using the formula

Answer 2

Answer:

a = 2

d = -1-2= -3

an = -77

a+(n-1)d=-77

2+(n-1)-3=-77

(n-1)-3=-77-2

(n-1)-3=-79

n-1= 79/3

n-1=26.333

n=27.33

since n is not a real or whole number

So,-77 is not a term of the AP
