Question

An arithmetic sequence has first term 25 and common difference 3. Find the 50th

Answer 1

Answer:

172

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 = 25 and d = 3, thus

$a_{50}$ = 25 + (49 × 3) = 25 + 147 = 172
