Answer:

62

Step-by-step explanation:

we have given a> 2

then \frac{2}{a}\ ,\frac{3}{a+1}\ ,\frac{4}{a+2}\ , \frac{5}{a+3}\ ,\frac{6}{a+4}

since it is given that a> 2

so a\equiv 2\ mod\ 4  a\equiv 2\ mod\ 5  a\equiv 2\ mod\ 6

a\equiv2 \left ( mod\ 2,3,4,5,6 \right )

a\equiv2 \left ( mod\ lcm\left ( 2,3,4,5,6 \right )\right )

a\equiv2 \left ( mod\ 60 \right )

then a=60n+2 where n is a positive integer

so smallest value of a is a=60×1+2=62
