Answer 1

Answer:

1,-1, 1, 1,9, 27,25,27,9,49

Answer 2

The next number is 49.

Step-by-step explanation:

Consider the provided series.

Observe the pattern.

(-1)×(-1) = 1 (First number of the series)

(-1)×(-1)×(-1) = -1 (Second number of the series)

1×1 = 1 (Third number of the series)  

1×1×1 = 1 (4th number of the series)  

3×3 = 9  (5th number of the series)  

3×3×3 = 27  (6th number of the series)  

5×5 = 25  (7th number of the series)  

5×5×5 = 125  (8th number of the series)  

Following the same patter will gives us the next number of the series.

7×7 = 49

Hence, the next number is 49.
