Question

Find the nth term of the following sequence: 7, 13, 19, 25,

Answer 1

Tn = 7 + (n - 1)*(6)

Explanation:

The explicit rule is in the form: Tn = a + (n - 1)*(d), where 'a' is the first term and d is the common difference.

The first term in the sequence is 7, so 'a' is 7. The common difference is 6

(13 - 7) = 6, hence 'd' is 6.

Therefore, Tn = 7 + (n - 1)*(6)

Answer 2

The answer of the next term is 31
