EXAMPLE

157 is a member because

157 = (97 + 101 + 103 + 107 + 109 + 113 + 127 + 131 + 137 + 139 + 149 + 151 + 157 + 163 + 167 + 173 + 179 + 181 + 191 + 193 + 197 + 199 + 211 + 223 + 227)/25 = 3925/25.

MAPLE

P:=proc(q) local n; for n from 13 to q do

if add(ithprime(n-k), k=-12..12)=25*ithprime(n) then print(ithprime(n));

fi; od; end: P(10^6); # Paolo P. Lava, Mar 17 2014
