Answer 1

Answer:

the required two numbers are -3, 9

Step-by-step explanation:

let the two numbers be X, Y

then the GP is

1, X, Y, -27

first term= a = 1

second term = ar= X

third term = ar^2= Y

forth term = ar^3= -27

=> 1ar^3= -27

=> r =-3

X = ar= 1×(-3)=-3

Y = a r^2 = 1 × (-3) ^2= 9

the required two numbers are -3, 9

the required two numbers are -3, 9resultant GP IS

the required two numbers are -3, 9resultant GP IS1, -3, 9 , -27
