Answer:
The expression for the other number is (n-1)
Step-by-step explanation:
we know that
The difference between two consecutive number is equal to 1
Let
x ----> the smaller of two consecutive number
n ----> the larger of two consecutive numbers
we have that

Solve for x

therefore
The expression for the other number is (n-1)
Answer:
A= -40
B= 16
C= 40
D= 50
Step-by-step explanation:
Answer:
Step-by-step explanation:
First we find n:
Tn = a+ (n-1)d
Here,
a=1 ,Tn =57
d=2 ( difference between numbers is 2)
Now,
57 = 1 + (n-1)2
57 = 2n -1
58/2 = n
Or n = 29
Now, We find sum :
Sn = n/2 { a+Tn}
= 29/2 { 1 + 57 }
= 29/2 ( 58)
= 29 x 29
= 841

Equation that can be used to find t
1 large table can take 15 people and there is only one large table.
So, we have:

1 small table can take 5 people and there are t small tables.
So, we have:

The room can accommodate 140 people.
So, we have:

This gives:

<em>The above expression can be used to determine the number of small tables</em>
