Answer 1

Answer:

56th term

Step-by-step explanation:

An = - 333

A = - 3

D = 6

N =?

An = a + (n-1) d

(n-1) = 55

n = 56

Answer 2

hiven,

A.P = -3,-9,-15..

a = -3

d = -9-(-3)

= -9+3

= -6

last term=-333

n=?

l= a+(n-1)d

-333 =-3+(n-1)-6

-333 =-3-6n+6

-333 =3-6n

-333-3=6n

-336=6n

n=-336/6
