Look at the ! brainliest and 5 star to the quickest right answer guys ive been doing homework all weekend and this is the last question end my sufferning b(1)=−2 b(n)=b(n−1)−7 find the 3rd term

-16

Step-by-step explanation:

Here, we have to use the general term to find the third term.

Given,

nth term is

b(n)=b(n-1)-7

Using   n=2, we get

b(2)=b(2-1)-7

    =b(1)-7

we are given      b(1)=-2

So,   b(2)=-2-7

             =-9

Now, using   n=3  in the nth term we get

b(3)=b(3-1)-7

    =b(2)-7

using    b(2)=-9 from above we get

b(3)=-9-7

    =-16

So, the 3rd term is    -16

Hey there!!

Given is an recursive formula :-

... b(n) = b(n-1) - 7

In this equation, 'n' is the number of the term we will need to find and '-7' is the common difference.

... b(1) = -2

We get to know that the first term is -2.

Now, we will find the 2nd term :-

... b(2) = b(2-1) - 7

... b(2) = b(1) - 7

We know b(1) is -2.

... b(2) = -2-7

... b(2) = -9

The second terms is -9 b(2) = -9

Now, let's find the third term :-

... b(3) = b(3-1) - 7

... b(3) = b(2) - 7

We know b(2) is -9

... b(3) = -9-7

... b(3) = -16

The third terms is -16.

Hence, the third term and the answer is -16.

Hope my answer helps!!

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
