Find the sum of the primes between 100 and 200, inclusive, that are 1 or 2 more than a perfect square.
+2095 Let's start by listing out the perfect squares that are between 100 and 200.
11^2=121
12^2=144
13^2=169
14^2=196
Now, let's see if the numbers that are 1 or 2 more than these squares are prime.
121+1=122 NOT PRIME
121+2=123 NOT PRIME
144+1=145 NOT PRIME
144+2=146 NOT PRIME
169+1=170 NOT PRIME
169+2=171 PRIME
196+1=197 PRIME
196+2=198 NOT PRIME
171+197=368

101 197 add them together ! *** edited ***
+2095 EP, I think it says "BETWEEN 100 and 200. . ." Doesn't that mean not including 100 and 200?
