Q. If a1=4 and an+1=(an)2+3 then find the value of a4.Answer:
Given information: We are given the first term of the sequence, a1=4, and the recursive formula for the sequence, an+1=(an)2+3. To find a4, we need to find a2, a3, and then a4 using the recursive formula.
Find a2: First, let's find a2 using the recursive formula and the given a1=4.a2=(a1)2+3=42+3=16+3=19.
Find a3: Next, we find a3 using the value of a2 we just found.a3=(a2)2+3=192+3=361+3=364.
Find a4: Finally, we find a4 using the value of a3.a4=(a3)2+3=3642+3=132,496+3=132,499.
