Question

Which recursive definition represents the sequence {4,6,8,10...}

Answer 1

We will use the equation: a subscript n = initial value + the rate x (n-1). The rate is adding 2 each time and the initial value is 4. The recursive definition for this sequence is a subscript n = 4+2(n-1). This simplified to a sub n=2n+2.

Answer 2

B) a1 = 4; an -1 + 2
