Question

Find the 43rd term of the sequence 27,24,21,18

Answer 1

The sequence is decreasing by 3 each time
So the formula would be y =27-3(x-1)
Plug in 43
Y =27-3(43-1)
Y = 27-3(42)
Y = 27-126
Y = -99
The 43rd term of the sequence would be -99

Hope this helps :)

Answer 2

The best answer is -99
