The sequence of number is 7.
7 times 37 and 37 plus 37 plus 37 plus 37 plus 37 plus 37 plus 37 are the same value: 259
The answer is 144, because 1+3 is 4 add 5=9 add 7=16 add 9=25+11= 36+13=49+15=64+17=81+19=100+21=121+23=144. And there you go
A potassium atom has 19 protons and 19 electrons, plus 20-22 neutrons. A rubidium atom has 37 protons and 37 electrons, plus 46-50 neutrons and so is bigger.
11 So: x = 37
-19 + 37 = 18.
-19 + 37 = 18
the answer is 37
37 + 4.6 - 19 = 22.6
38+37+11+8=94
associative property
The Least Common Multiple (LCM) for 19 40 37 11 is 309,320.
(11 × 60) + 37 = 697
X + 11 = 37. subtract 11 from both sides; X = 37 - 11 = 26.
-187
