Q. If a1=1 and an+1=(an)2−3 then find the value of a4.Answer:
Given Sequence and Formula: We are given the first term of the sequence, a1=1, and the recursive formula an+1=(an)2−3. We need to find the value of a4.
Find a2: First, let's find a2 using the recursive formula with n=1.a2=(a1)2−3=(1)2−3=1−3=−2.
Find a3: Next, we find a3 using the recursive formula with n=2.a3=(a2)2−3=(−2)2−3=4−3=1.
Find a4: Finally, we find a4 using the recursive formula with n=3.a4=(a3)2−3=(1)2−3=1−3=−2.
