The first term of an arithmetic sequence is -5, and the tenth term is 13. Find the common difference. 1.8
2
8/9

d = 2

Step-by-step explanation:

The n th term of an arithmetic sequence is

= a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 5 and a₁₀ = 13, thus

a₁ + 9d = 13, that is

- 5 + 9d = 13 ( add 5 to both sides )

9d = 18 ( divide both sides by 9 )

d = 2

(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

answer: 8d

step-by-step explanation:

45+5= 50+5=55+5=60
