Only 63 is a composite. 63 = 3 x 3 x 7 The other three numbers (13, 31, 61) are all prime numbers.
The prime numbers between 65 and 75 are: 67, 71 and 73

3*3*7=63
2 is a prime because it can only be multiplied by 1x6 but 63 isn't
My guess is 65. I don't know what sequence the first, third numbers are but observing the others it is going 61...63.....65....67
