Question

DIRECTIONS: Each number if 4 less than 3 times the previous number.

Starting with the number 10, build a sequence of 5 numbers.

Answer 1

10, 26, 74, 218, 650

Explanation:

n * 3 - 4

Answer 2

The sequence of 5 terms is: 10, 26, 74, 218, 650

Explanation:

By following the instructions, we can build the sequence by doing:

`a_n= 3\,a_(n-1)-4`

So, using this formula and starting with 10 we get

`a_1=10\\a_2=3\,(10)-4=26\\a_3=3\,(26)-4= 74\\a_4=3\,(74)-4=218\\a_5=3\,(218)-4=650`
