Arithmetic Progression (AP) is a sequence of numbers in order that the common difference of any two successive numbers is a constant value. Example 15 Find the sum of first 24 terms of the list of numbers whose nth term is given by an = 3 + 2n Given an = 3 + 2n Now 1st term = a1 = 3 + 2 (1) a = 3 + 2 a = 5 2nd term = a2 = 3 + 2 (2) = 3 + 4. We have an=3+4n Substituting n+1 we get an+1=3+4 (n+1)=4n+4+3=4n+7 Common difference d=an+1-an=4n+7-4n-3=4 Since the common difference d is constant they are in an arithmetic progression.

So with each additional term, you have multiplied a number by 3 one more time. Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. Also find s Share with your friends.
