Transcribed Image Text: 7.
Given the recursive sequence an = an-1 – 19 for all n > 1, where ao =-14,
i. Find a1, a2, a3 using the recurrence relation.
ii. Use either a shortcut (that we talked about in the notes) or iteration to obtain an explicit
formula for an. If you use a shortcut, specify whether the recurrence sequence is arithmetic or
geometric. If you use iteration, explain your reasoning.
iii. Use the explicit formula from part (ii) to find a500-
