Q. If a1=2 and an+1=(an)2+2 then find the value of a4.Answer:
Calculate a2: Given the recursive sequence where a1=2 and an+1=(an)2+2, we need to find the value of a4. We start by finding a2 using the given formula.a_{2} = (a_{1})^2 + 2\(\newline = (2)^2 + 2 = 4 + 2 = 6\)
Calculate a3: Next, we find a3 using the value of a2 we just found.a_{3} = (a_{2})^2 + 2\(\newline = (6)^2 + 2 = 36 + 2 = 38\)
Calculate a4: Finally, we find a4 using the value of a3.a4=(a3)2+2=(38)2+2=1444+2=1446
