Katyanochek1 [597]

Answer:

1.1.1) -61

1.1.2) Term 42

Step-by-step explanation:

Tn= dn (difference) + t0 (term 0)

Tn= -4n+ 11

You can now take this general rule to find out the other terms.

Tn= -4(18)+11

Tn= -61

And the term -157

Tn= -4n+11

-157= -4n + 11

-157 - 11= - 4n

-168= -4n

-168/-4= n

42= n

Can someone help me I can't remember how to do ratios
omeli [17]

3 casseroles feeds 15 people

The ratio is 3:15

If you divide each of those by 3, youll find that 1 casserole feeds 5 people

1 : 5 is the ratio.

Divide 30 by 5 = 6

6 casseroles feeds 30 people.

6 : 30

35 divided by 5 = 7

7 casseroles feed 35 people

7 : 35
