Question

Find the 30th term of the arithmetic sequence with a first term of 4 and a comman difference of 8 ​

Answer 1

236

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 = 4 and d = 8, thus

`a_(30)` = 4 + (29 × 8) = 4 + 232 = 236
