i used the formula

Answer 8

It wasnt it

Answer 9

a_1 = 1, it tells us that

a_2 = 4* a_1 - 1 ----> a_2 = 4-1
so a_2 = 3

a_3 = 4* a_2 - 1 ----> a_3 = 12 - 1
so a_3 = 11

a_4 = 4 * a_3 - 1 ---> a_4 = 44 - 1
so a_4 = 43

a_5 = 4 * a_4 - 1 ----> a_5 = 172 - 1
so a_5 = 171


so the first 5 numbers in the sequence would be 1, 3, 11, 43, 171

Answer 10

your arithmetic sequence calculator that you linked does not work for this problem because the sequence is not arithmetic, it's recursive
