Question

Write an explicit formula for an; the nth
term of the sequence 6, 12, 18, ....

Answer 1

The answer your looking for is 6n, it starts with six and goes up by six each time.

Answer 2

F(n) = 6n

Explanation:

An explicit sequence goes by the pattern: A0 + (n-1)d, where A0 is the starting term, n is the nth term in the sequence, and d is the common difference. The explicit formula for this sequence is F(n) = 6 + 6(n-1), or 6n
