GATE ECE 2015 Set 3 Signals and Systems - Discrete Time Signal Z Transform Question 23 English

$$4{\left( { - {1 \over 3}} \right)^n}u\left[ n \right] - 5{\left( { - {2 \over 3}} \right)^n}u\left[ n \right]$$

$$5{\left( { - {2 \over 3}} \right)^n}u\left[ n \right] - 3{\left( { - {1 \over 3}} \right)^n}u\left[ n \right]$$

$$5{\left( {{1 \over 3}} \right)^n}u\left[ n \right] - 5{\left( {{2 \over 3}} \right)^n}u\left[ n \right]$$

$$5{\left( {{2 \over 3}} \right)^n}u\left[ n \right] - 5{\left( {{1 \over 3}} \right)^n}u\left[ n \right]$$
