How can you connect five resistors of values 2ohms 3ohms 4ohms 5ohms 6Ohms Whose equivalent resistance will be 7 ohms?

well shortly

connect in series the resultant of 3 and 6 with 2 ---->(3 6)+2=4

now connect the resultant of step 1.) in parllel with 4 ----> 4 4 = 2

now connect in series the resultant of step 2.) with 5 -----> 5+2 = 7

note :- the numbers are darkened so that you may not confuse given values with the obtained results in each step
