Answer 1

Answer:

The answer is 728

Step-by-step explanation:

i ) 3¹+ 1 = 3 + 1 = 4

ii ) 3² - 1 = 3 × 3 - 1 = 9 - 1 = 8

iii ) 3³ + 1 = 3 × 3 × 3 + 1 = 27 +1 = 28

iv ) 3⁴ - 1 = 3 × 3 × 3 × 3 - 1 = 81 - 1 = 80

v ) 3 ^5 + 1 = 3 × 3 × 3 × 3 × 3 + 1 = 243 + 1 = 244

vi ) 3 ^6 - 1 = 3 × 3 × 3 × 3 × 3 × 3 - 1 = 729 -1 = 728
