Easy!!!
You're all wrong! it's not an arithmetic sequence! you have just put logic into it and just add & minus and use your common sense!!
But the pattern is a pythagorean triple!! so the answers are:
√5 and 3612!!
Why?
simply because terms 1,2,3 form a pythagorean triple!
Check!
(√5)² + 2² = 3² is the equation true?
5 + 4 = 9
9=9 TRUE!!!
so the answer is √5
next terms!
3 4 and 5
Check:
3² + 4² = 5²
9+16=25
25=25 TRUE!!
Next!
5, 12, 13
Check:
5²+12²=13²
25+144= 169
169=169 TRUE!
Next!
13,84,85
13²+84²=85²
169 + 7056 = 7225
7225=7225 TRUE!
LAST!!
85,3612,3613
85² + 3612²= 3613²
7225 +13046544 = 13053769
13053769 = 13053769 TRUE!!!
SO the answers are!!
√5 and 3612!
That's all!! ^_^!!
