10 Work out the first three terms in each sequence. first term is 5 rule is multiply by 2 then subtract 8 term-to-term a rule is subtract 4 - then multiply by 2 term-to-term b first term is 12 2 first term is -8 term-to-term rule is add 4 then divide by 2 11 The first term of a sequence is 22. The term-to-term rule is divide by 2 then subtract 3. Show that the first term in this sequence which is a negative number is -2.
