Question 4
Calculate the value of n for the given terms in sequences with the following nth term formulae:
| (a) | \( 6n + 2\) | \( \mathrm {term} = 56\) | (b) | \( 2n - 1\) | \( \mathrm {term} = 11\) | (c) | \( 3n + 22\) | \( \mathrm {term} = 58\) |
| (d) | \( 5n - 4\) | \( \mathrm {term} = 21\) | (e) | \( 7n + 9\) | \( \mathrm {term} = 65\) | (f) | \( -3n - 6\) | \( \mathrm {term} = -27\) |
| (g) | \( 4n + 3\) | \( \mathrm {term} = 43\) | (h) | \( -9n + 24\) | \( \mathrm {term} = -21\) | (i) | \( 12n - 6\) | \( \mathrm {term} = 126\) |
| (j) | \( 8n - 5\) | \( \mathrm {term} = 59\) | (k) | \( -15n + 42\) | \( \mathrm {term} = -63\) | (l) | \( 13n + 5\) | \( \mathrm {term} = 83\) |
