Question

Which recursive formula can be used to represent the sequence2, 4, 6, 8, 10, ...?a₁ = 2O A.3n = 8-1-22₁ = 22n = 3-1 +2a₁ = 22n = 3-1-231 = 02 = 3-1+2OB.О с.O D.

Answer 1

Answer: B

Explanation:

The given sequence is expressed as

2, 4, 6, 8, 10.....

The first term, a1 = 2

Common difference = 4 - 2 = 6 - 4 = 8 - 6 = 2

Each term is gotten by adding 2 to the previous term. Thus, the recursive formula is

B. a1 = 2

an = a(n - 1) + 2
