**Reiny**, Tuesday, April 23, 2013 at 8:15amsince a and b are consective integers we could say that

a = b+1

then let the difference be

(b+1)^2 - b^2 > 22

b^2 + 2b + 1 - b^2 > 22

2b > 21

b > 10.5

so b has to be 11

a = 12

So a+b = 23

check: 12^2 - 11^2 = 144-121 = 23 which is > 22

try another value:

13^2-12^2 = 25

11^2-10^2 = 21
