Insert 5 arithmetic means between -1 and 11

Mathematics
1 answer:
Anni [7]3 years ago
7 0

Answer:

Step-by-step explanation:

-1 1 3 5 7 9 11

That's the answer. If you need a method or a formula, that's a little harder.

L = a + (n - 1)*d

a = -1

L = 11

n = 7

or n is the hard part. If you have 5 means, then you have 6 spaces. So n must be 7 in all

11 = -1 + (7 - 1)*d                   add 1 to both sides. Combine the brackets

11+1 = -1+1+ 6*d

12 = 6d                               divide by 6

12/6 = d

2 = d

What this tells you is that each term has 2 added to it to get to the next one.

attashe74 [19]
The area for rectangle is (l x w) or (length times width) or (length x width) 

*just in case you get confused

so the length is 10, and the width is 2.5 so you plug in.

10 x 2.5 = 25

your answer is 25 mm²
