find the smallest integer a>2 such that
2/a, 3/a+1, 4/a+2, 5/a+3, 6/a+4
please steps by steps
could you give me more detail? because i just learning it.
2|a,3|(a+1),4|(a+2),5|(a+3),6|(a+4)
a=2b=3c-1=4d-2=5e-3=6f-4
a-2=2(b+2)=3(c-1)=4(d-1)=5(e-1)=6(f-1)
a-2=[2,3,4,5,6] * k = 60k
a=60 k +2
ex:
62,122,182,242.....
