Answer:
- 7y +3 =-25
-7y=-25—3
-7y=-28
-7y÷-7= -28÷-7
y=4
Step-by-step explanation:
Take +3 to the side so that your variable and a constant is on their own sides. When a number goes over the equals sign the sign changes at becomes the inverse that's why l said - 3. You now calculate - 25—3 equals 28 then divide by 7 to find y and your y is 4.

Answer:
for 
Step-by-step explanation:
Given
-- First Term
--- half common difference
Required
Find the recursive rule
First, we calculate the common difference

Multiply through by 2


The second term of the sequence is:

The third term is:

So, we have:


Substitute f(1) for 3

Express 1 as 2 - 1

Substitute n for 2

Similarly:

Substitute f(2) for 11

Express 2 as 3 - 1

Substitute n for 3

Hence, the recursive is:
for
