Find the nth term of this number sequence15, 12, 9, 6....​

Mathematics

Ann [662]3 years ago

Answer:

You only have four terms so n can only be 1, 2, 3 or 4!

I think you mean: What is the nth term of the sequence 15, 12, 9, 6, …?

The ellipsis (…) tells us that the sequence continues.

This is an arithmetic sequence, where the general term is:  a+bn  

n=1:a+b=15  [Eq. 1]

n=2:a+2b=12  [Eq. 2]

Subtracting Eq. 1 from Eq.2:  b=−3  

Substituting this into Eq. 1:  a−3=15⇒a=18

Thus the nth term is:  18−3n

Step-by-step explanation:

3m - (m^2 + n); if m = 2 and n 19
deff fn [24]

Answer:

- ( 17 )

Step-by-step explanation:

m = 2

n = 19

m^2

= 2^2

= 2 x 2

= 4

3m

= 3 x 2

= 6

3m - ( m^2 + n )

= 3m - ( m^2 + n )

= 6 - ( 4 + 19 )

= 6 - 23

= - ( 17 )

5 2/3 divided by 2 im terrible at fractions
Degger [83]
You can make the mixed number 5 2/3 an improper fraction, which is the number in the numerator is larger than the number in the denominator.
Multiply, Add, and Keep the denominator are the steps you need to take.
Multiply the denominator by the whole number and then add the number in the numerator, while keeping the denominator. 5*3+2=17>>> 17/3 is the improper fraction.
17/3 ÷ 2 is the resulting equation.
When you divide fractions, you have to multiply by the reciprocal. 2/1 is the whole number 2, but in fraction form. The reciprocal is 1/2 because your just flipping the numerator and the denominator.
17/3 * 1/2 is the new equation.
When you multiply fractions, you multiply straight across.
17/3 * 1/2 = 17/6 or 2 5/6 is your answer.
