Answer 2

hye

=================================

what is a twin prime?

=> it is a pair of prime number ,where one prime is 2 more or less than the other prime

=>the formula for finding twin prime is  p +(p+2)

now lets see whther these numbers are twin prime 

=> 1)36

=> p +(p+2) = 36

=>2p +2 = 36

=>2p = 34

=>p = 34/2 = 17

other number is 2+p = 17+2 = 19

so 34 = 17,19

2)84 

=> p +(p+2) = 84

=>2p +2 = 84

=>2p = 82

=> p = 41

other number is 2 + p = 43

=>84 = 41,43

3)120

=> p +(p+2) = 120

=>2p +2 = 120

=>2p =118

=>p = 59

other number 2+p = 61

=>120 = 59,61

4)144

=> p +(p+2) = 144

=>2p +2 = 144

=>2p = 142

=> p = 71

other number is 2+p = 73

=>144 = 71,73
