Question

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 156, 153, 150, ... Find the 30th term.

Answer 1

Answer: 69

Explanation:

Equation for sequence:

nth term = a + d(n-1) #d is the difference between the terms, a is the first term, n is the term number

Therefore,

nth term = 156 + 3(n-1)

30th term = 156 + -3(30 - 1) = 69
