Answer:

Step-by-step explanation:
Given
Sequence = Consecutive Odds

Required
The sum of the terms
A sequence of odd number has a difference of 2. So, the sequence is represented as:

Add up all terms in the sequence


Common difference = 6 - 2.5 = 3.5
(B) recursive formula can be written as
U(n+1) = U(n) + 3.5n
where value of n is 0 to infinity
The answer is Either 2 18 or 21
The answer is (-2, -1.5, 0, 2/5, 3/4)
9.73, or 9.73x10^-3, hope this helped!
