Question

Select the formula for the xth term of the sequence.
3, 11, 19,

Answer 1

8n - 15

Explanation:

for finding the nth term we need to figure out the difference between the numbers:

3,11,19 = difference of 8

multiples of 8:

8,16,24,32,40...

the nth term would be 8n - 5 because in order to get to 3 from 8, we minus 5
