Intermediate June 2018 Unit 1 Q6
6.
(a) The table below shows the first five terms of a sequence of numbers.
| Term | \(t_1\) | \(t_2\) | \(t_3\) | \(t_4\) | \(t_5\) |
| Value | 2 | 5 | 8 | 11 | 14 |
Circle the correct equation that connects terms \(t_6\) and \(t_7\). [1]
\(t_6 = t_7 + 3\) \(t_7 = t_6 + 14\) \(t_7 - t_6 = 1\) \(t_7 = t_6 - 3\) \(t_7 = t_6 + 3.\)
(b) The \(n\)th term of another sequence is given by \(2n - 11\).
Write down the value of,
Write down the value of,
(i) the 10th term, [1]
(ii) the 3rd term. [1]
