Step-by-step explanation:
The nth term just mean how to work out the next number in he series. In this series of numbers, you have to square three n and add it onto 10 n to do this.
N is the term- the number it comes in the sequence.
Example:
2 3 4 5 6
2= the first terof the sequence
3= second term
4=3rd term
And so on
To work out what the next term is (6th term) you use this expression:
N+1
The first term is 2. As it is the first n=1. 1+1=2 so that works
The seco d term is 3. As it is the second term n=2. 2+1+3 so that works
And so on
This might help
But you have to do the rest

Answer:
10 inches
Step-by-step explanation:
Use the formula for the area of a trapezoid. Fill in the given information and solve for the unknown.
A = 1/2(b1 +b2)h
50 in² = (1/2)(3 in +7 in)h
50 in²/(5 in) = h . . . . . . . . . . divide by the coefficient of h
10 in = h
The height of the trapezoid is 10 inches.

Answer:
$1.2
Step-by-step explanation:
Given the total cost, in dollars, given by the function c(p) = 1.2p.
If p = 1
c(1) = 1.2(1)
c(1) = $1.2
If p = 2
c(2) = 1.2(2)
c(2) = $2.4
If p = 3
c(3) = 1.2(3)
c(3) = $3.6
If p = 4
c(4) = 1.2(4)
c(4) = $4.8
Common difference = c2 - c1 = c3 - c2 = c4 - c3
Common difference = 2.4 - 1.2 = 3.6 - 2.4 = 4.8 - 3.6 = 1.2
Hence the common difference is $1.2
