Find the 7th term in the sequence
-5, -1, -5, -25,...
Hint: Write a formula to help you.
1st term · Common Ratio(desired term – 1)
Enter

Step-by-step explanation:

Given sequence is -5, -1, -5, -25,..

In any arithmetic series  nth term is given by  a + (n-1)d

where a is the first term

and d is the common difference.

 d = nth term - (n-1)th term

For the given  series

a = -5

lets take nth term as 2nd term and 1st term as (n-1)th term

d = -1-(-5)= -1+5 = 84

n th term = a + (n-1)d

using the formula for nth term

4th term = 5 + (4-1)8 = 29

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
