Transcribed Image Text:4. Consider a sequence aj = 3 and an+1 = v V12 + an for each n > 1. (a) by 4. Show by induction that {an} is monotone increasing and bounded above
Expert Solution
Step 1

Given that a1=3 and an+1=12+an for each n1

Also, the sequence an is monotonic increasing and bounded above by 4.

This implies that the sequence an is convergent. Also, the sequence is the sequence of positive terms.

The objective is to find limnan
