Step-by-step explanation:

Begin with the equation . Let's first find .

For each time increases by 2 (the rows skip by 2), increases by 6. Since the relationship is linear, if were to increase by just 1 (half of 2), would increase by 3 (since we halve each component). Therefore, .

To find (the y-intercept), we plug in the first value of we are given and notice the result. In this case, . However, the first value of is 1, so we must subtract 11 so that the first term is 1. Hence, .

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
