Question

Find the 50th term of an arithmetic sequence 5, 10, 15,
20, 25,...​

Answer 1

a₅₀ = 250

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 = 5 and d = a₂ - a₁ = 10 - 5 = 5 , then

a₅₀ = 5 + (49 × 5) = 5 + 245 = 250
