What are the first five terms of the arithmetic sequence defined explicitly by the formula an=14-3n a. -3, 0, 3, 6,9 b. 14, 17, 20, 23, 26 c. 14, 11, 8, 5, 2 d. 11, 8, 5, 2, -1

Option D. is the answer.

Step-by-step explanation:

Explicit formula of the arithmetic sequence is defined by the formula

Where = nth term of the sequence

n = number of term

We have to find the first five terms of this sequence.

For n = 1,

For n = 2,

For n = 3,

For n = 4,

For n = 5,

Therefore, the sequence will be 11, 8, 5, 2, -1............

Option D. will be the answer.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
