Answer 1

The sequence goes 4, 9, 25, 49, 121.

This is because, the sequence takes the prime numbers in order and then squares them. 2^2 is 4, 3^3 is 9, 5^2 is 25, 7^2 is 49, and 11^2 is 121. So if you want to go ahead you just take the next prime number and you would square the number and you would get the next number.

Answer 2

64, 144 This is the answer
