Question

How do I solve this arithmetic sequence?

Answer 1

7 times 50=350

Explanation:

Answer 2

a₅₀ = 252

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 = 7 and d = 5 , then

a₅₀ = 7 + (49 × 5) = 7 + 245 = 252
