What is the recursive definition and explicit formula of the sequence 3, 5.5, 8, 10.5, 13, 15.5? I know the pattern is +2.5

= + 2.5

Step-by-step explanation:

This is an arithmetic sequence with common difference d = 2.5

The recursive formula allows any term in the sequence to be found by adding d to the previous term, thus

= + 2.5 ← recursive formula with a₁ = 3

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
