Answer:
a) The missing terms are 9, 13, 21 and 25.
b) If we know that 
and 
, then the n-th term of the sequence is represented by 
.
Step-by-step explanation:
a) Given that elements of the sequence are found by increasing by the same amount, we infer that elements are part of an arithmetical progression. The rate of progression is now determined:
The missing terms are:
The missing terms are 9, 13, 21 and 25.
b) The formula for the arithmetical progression is represented by the following formula:
(1)
Where:
- First element of the sequence.
- Indicator associated with the element of the sequence.
- Progression rate.
If we know that and , then the n-th term of the sequence is represented by .

I need that urgently.
The answer would be to divide 1030 by 50 and you would get 21 coaches not 20 because 50x20=1000 and there are 30 remainder. Therefor, you would need that extra coach with some seats left to spare. so your answer is 21 coaches
Answer:
Width is 10 Length is 20
Step-by-step explanation:
Perimeter = 60
Length = W + 10
P = 2L + 2W Write the equation for perimeter
60 = 2(W + 10) + 2W Substitute your variables
60 = 4W + 20
- 20 - 20 Subtract 20 from both sides
40 = 4W Divide both sides by 4
10 = W
