Find the 15th term in the following arithmetic sequence : 1, 6, 11, 16, ... Hint: Write a formula to help you. 1st term + common difference(desired term - 1)​

a₁₅ = 71

Step-by-step explanation:

The nth term of an arithmetic sequence is

= a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 1 and d = 6 - 1 = 5 , then

a₁₅ = 1 + (14 × 5) = 1 + 70 = 71
