What are the first eight numbers in a fibonacci sequence when n is equal to 1? a. 1,2,3,4,5,6,7,8 c. 3,0,2,3,2,5,5,7 b. 1,1,2,3,5,8,13,21 d. 1,1,2,2,3,4,5,7

The Fibonacci sequences are a series of numbers in which the next number is found by add up the two previous numbers together.
The Fibonacci sequence increase and starts at 0 or 1

It can't be A. because 4th number is not the sum of 2+3 (the previous numbers)
It can't be C. because it starts with 3 with the next number decreasing instead of increasing
It can't be D. because the 4th number is not the sum of 1+2

So it must be (B. 1,1,2,3,5,8,13,21 ) because it follows the rules.

The answer is 4.7
