ExtremeBDS [4]

Answer:

-9

Step-by-step explanation:

We are summing the 3rd 4th and 5th terms because k goes from 3 to 5

The third term is

-2(3) +5 = -6+5 = -1

The fourth term is

-2(4) + 5 = -8+5 = -3

The fifth term is

-2(5) +5 = -10 +5 = -5

Add these 3 terms together

-1+-3+-5 = -9

Write an equation for the nth term of the arithmetic sequence. -6,-9,-12,-15
poizon [28]

Answer:

a_{n} = - 3n - 3

Step-by-step explanation:

The nth term of an arithmetic sequence is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 6 and d = a₂ - a₁ = - 9 - (- 6) = - 9 + 6 = - 3 , then

a_{n} = - 6 - 3(n - 1) = - 6 - 3n + 3 = - 3n - 3
