1 Determine whether give common difference if it is geometri

1. Determine whether give common difference; if it is geometric, find common ratio n sequence is arithmetic, geomctric or neither. If the sequence is arihmeic, find the n sequence is arithmetic, geometric or neither. If the sequence is arithmetic, find the

Solution

Here the sequence is geometric as the ratio is common ratio.

a_n = (4/3)ⁿ

Common ratio = r = 4/3

a_n = (4/3)(4/3)^n-1
