zmey [24]

(a) The nth term of the sequence is given by A(n)=195 + (n - 1)10.

(b) The 12th term of the sequence is A(12) = 305.

<h3>What is an arithmetic sequence?</h3>

One arithmetic progression with a common difference of 2 is the sequence 5, 7, 9, 11, 13, 15,...

The term "finite arithmetic progression" or "arithmetic progression" refers to a limited segment of an arithmetic progression.

A mathematical sequence has the following structure: a, a+d, a+2d, a+3d, etc., up to n terms. The initial term is a, the shared distinction is d, and n is the total number of words. Find the AP, the first term, the number of terms, and the common difference for the computation using the arithmetic sequence formulae. To determine the nth term, sum, or common difference of a given arithmetic sequence, many formulae related to arithmetic series are utilized.

A(n)=195+(n-1)10

The given arithmetic sequence is 195, 205, 215, 225,.....

The first term a =195

The common difference d= 205-195

d =215-205

d =225-215

So, d = 10

(a) The nth term is given by

A(n)=a+(n-1)d

A(n)=195+(n-1)10

(b) For n=12, the 12th term is given by

A(12)=195+11(10)

A(12)=305

Therefore, A(n)=195+(n-1)10

And A(12)=305

Answer:

Not enough information.

Step-by-step explanation:

The 25 students absent is irrelevant. We still don't know the total number of students at Riverside Elementary School.

A sequence is n(n - 1)<br><br>Which term is 156? The ___th Term​
Bond [772]

Answer:

n(n-1) =156

n^2-n=156

n^2-n-156=0

(n-13) (n+12) =0

so n=13 because it's an ordinary number and can't be negative

Answer:

D

Step-by-step explanation:

The slope = 4/2 = 2

and one point  on the graph ( point B)  is (5, 6)  so point-slope equation is

Salsk061 [2.6K]
Divide both sides by -2. Treat the '<' as an equal sign.
x > -5. You flip the sign since you divided by a negative number.
