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) \( 13n + 5\) \( \mathrm {term} = 83\)
