Question

An arithmetic sequence has first term 30 and common difference 3. Find

the 50th term of the sequence

Answer 1

177

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
