Elias’s teacher has given him a rectangle that is 15 feet by 20 feet. she has asked him to create a new rectangle using a scale factor of 8/3. elias says that will be a reduction because the scale factor is a fraction. is he correct? explain.

Elias is not correct. The new rectangle will be an enlargement because the scale factor is greater than 1. To be a reduction, the scale factor must be between 0 and 1.

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 .
