The common difference is the constant that you get when you get the difference between any term and the one preceding it. In this case:
(3--4)=(10-3)=(17-10)=d=7
To find the answer, all you must do is convert 14% into a decimal by moving the decimal point two units to the left which will give you the number: 0.14. Multiply 21 by 0.14 and you should get your answer: 2.94. This means 14% of 21 is 2.94.
All angles in a triangle add up to 180
So 79+37=116
180-116=64
Y=64
Hope this helps
