Answer:
- 5, 2, 9, 16 and d = + 7
Step-by-step explanation:
to obtain the first four terms substitute n = 2, 3, 4 into the recursive formula
f(1) = - 5 ← given
f(2) = f(1) + 7 = - 5 + 7 = 2
f(3) = f(2) + 7 = 2 + 7 = 9
f(4) = f(3) + 7 = 9 + 7 = 16
common difference d = 16 - 9 = 9 - 2 = 2 - (- 5) = 7
Since the ratio of red to blue paint is 6 and 5. And 15 pints are blue you do 15 divided by 5 and it is 3. So you would do the same for red and it will be 18 so you do 18 plus 15 which is 33 pints in total
1+1 is equal to 3-1. 1+1=2. 3-1=2. 2=2
Simplify the square root

Separate the numbers in the square root to look like this

Because three is squared, it cancels out the square root
