• First of all make sure to number (n) your terms (t) in the sequence above • Then work out the difference (d) which Is +7 each time •hence the base (b) for your nth term wIll be the difference x n = 7n •now you will check to see If the base works, If not you wIll alter it by addIng or subtracting a certaIn amount. In thIs case we are always 1 hIgher, so we IIst need to subtract 1 from the base. nth term = 7n -1 (n) 1. 2. 3. 4. 5. (t) 6. 13. 20. 27. 35. (d) +7 +7 +7 +7 (b) 7 14 21 28 35
