Question

Can someone help me with this math homework please!

Answer 1

option 3 is the answer.

Explanation:

3, - 6, 12, - 24, 48, .....

Here,

f ( 1 ) = 3

f ( 2 ) = - 6

f ( n + 1 ) = - 3 f ( n )

f ( 1 + 1 ) = - 3 f ( 1 )

f ( 2 ) = - 3 x 3

f ( 2 ) = - 9

This recursive formula is not correct.

f ( n + 1 ) = - 2 f ( n )

f ( 1 + 1 ) = - 2 f ( 1 )

f ( 2 ) = - 2 ( 3 )

f ( 2 ) = - 6

This recursive formula is correct.

Answer 2

f(2)= f(1+1) ,where n= 1

=-6

= -2×3

= -2f(1)

f(n+1 )= -2f(n)

OPTION C is the correct answer
