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