Question

hi
plz answer this fast​

Answer 1

welcome to the concept of Ap

4,0,-4,-8,....48

a = 4

d = 0-4 = -4

an = 48

we know that

an = a+(n-1) d

48= 4(n-1)× (-4)

44 = (n-1)(-4)

-11 = n-1

n= -10

but no of terms cannot be negative

if in yr question last term is -48

then ,...

an = a+(n-1)d

n = 12

I hope it help you ❤️
