Question

An arithmetic sequence has first term 30 and common difference 3. Find
the 50th term of the sequence

Answer 1

Answer:

177

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, thus

$a_{50}$ = 30 + (49 × 3) = 30 + 147 = 177
