Answer:
4.46
Step-by-step explanation:
(11.5 + x) + 5% = 16.8
11.5 + x = 16.8 - 5%
x = (16.8 - 5% ) - 11.5
x = 15.96 - 11.5
x = 4.46
From the explicit formula:
an=3+(n-1)8
simplifying this we get:
an=3+8n-8
an=8n-5
thus
the recursive formula is:
an=an-1+
the missing part is the common difference which is 8
