Question

A list of numbers represents the following pattern:
For each number after the first, multiply the previous number by itself, and then subtract that number. Which list does NOT represent that pattern?

A. 1,1,1,1, and so on
B. 2,2,2,2, and so on
C. 3,6,30,870, and so on
D. 4,12,132, 17, 412, and so on

Can somebody please show me in detail on how to solve this problem by getting the correct answer?

Answer 1

Can someone please help me?

Answer 2

A.. Because then number after 1 have to multiply the previous number (1) so 1*1=1. Then it subtracts the previous number 1-1=0. So the list would be 1,0,0,0,0 so on... So A is incorrect
