GD morning everyone, hope all fine ☺️
Have a fabulous day...☺️​

Answer 1

Answer:

now a2=4. and A3 = -11

d= a3-a2

d= -11 - 4

d= - 15

now a = a2-d

a = 4- (-15)

a= 4 + 15

a = 19

now AP is 19, 4, -11, now you will easily find other terms by add d to last term

-11 + (-15 ) = -26

-26 + (-15) = - 41

now so is 19, 4, -11,-26,-41...
