Question

the first three terms of a sequence are given round to the nearest thousandth if necessary 4,12,20,... Find the 41st term

Answer 1

4, 12, 20

Series would be: 4 + 8 * (n - 1) = 4 + 8n - 8 = 8n - 4

n = 1 ==> 4

n = 2 ==> 12

n = 3 ==> 20

n = 41 ==> 4 + 8 *(41 -1) = 4 + 8 * 40 = 4 + 320 = 324

Answer:

324
