Question

What is the ninth term in the sequence? bn = 18 - 2n

Answer 1

The ninth term of the sequence bn, will be given by the substitution of n = 9 in the general expression of the sequence bn. Therefore, we have to replace, the ninth term will be:
 b9 = 18-2 * (9) = 18-18 = 0
 The ninth term of the sequence is 0.
