Answers

Answer 1
Answer:

Answer:

d = 2

Step-by-step explanation:

The n th 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 = - 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
