Introduction to Arithmetic Progressions and nth term

Three numbers a, b and c are in geometric progression. If 4a, 5b and 4c are in arithmetic progression and a+b+c=70 , then the value of |c-a| is equal to

Find the sum of given Arithmetic Progression 4+8+ 12+....+ 64

Define an arithmetic progression.

The 5^("th") and the 31^("th") terms of an arithmetic progression are, respectively 1 and -77 . If the K^("th") term of the given arithmetic progression is -17 , then the value of K is

If the 2^(nd),5^(th) and 9^(th) terms of a non-constant arithmetic progression are in geometric progession, then the common ratio of this geometric progression is
