Question

Quizplus · Accepted Answer

We know that the common difference (d) is 7, and the first term (a) is 4. The formula for the nth term of an arithmetic sequence is: an = a + (n-1)d Substituting the given values, we get: an = 4 + (n-1)7 an = 4 + 7n - 7 an = 7n - 3 Therefore, the formula for the sequence in terms of a_n is: a_n= 7n - 3
