Timed final a sequence is defined by the explicit formula an = 3^n + 4. which recursive formula represents the same sequence of numbers?

= 3 - 8, with = 7

generate the first few terms of the sequence

= 3 + 4 = 7

= 3² + 4 = 9 + 4 = 13

= 3³ + 4 = 237 + 4 = 31

= + 4 = 81 + 4 = 85

the sequence is 7, 13, 31, 85, .....

Checking the recursive formulae given the one that generates the sequence is

= 3 - 8 with = 7, as

= (3 × 7 ) - 8 = 21 - 8 = 13 ← correct

= (3 × 13 ) - 8 = 39 - 8 = 31 ← correct

= (3 × 31 ) - 8 = 93 - 8 = 85 ← correct
