Since arithmetic and geometric sequences are so nice and regular they have formulas. A n a 1 n 1d. So we want to have u n 1 a a u n a a u n b a.
In mathematics an arithmeticogeometric sequence is the result of the term-by-term multiplication of a geometric progression with the corresponding terms of an arithmetic progressionPut more plainly the nth term of an arithmeticogeometric sequence is the product of the nth term of an arithmetic sequence and the nth term of a geometric one.
A 0 a. An arithmetic sequence or arithmetic progression is a sequence in which each term is created or obtained by adding or subtracting a common number to its preceding term or value. Similarly If a b and c are three terms given to be in GP. Since we get the next term by adding the common difference the value of a2 is just.
