so for 1 subtitute into the equation and get 5+(1-1)3 or 5+0 or 5
for 2 5+(2-1)3 5+3 or 8
3
5+(3-1)3 5+2(3) 5+6 11
The next three terms in the sequence are 14, 17, and 20. Each term is calculated using the formula a n = 5 + ( n − 1 ) × 3 . Starting from 5 for n = 1 , these values follow an arithmetic pattern of increasing by 3 for each step up in n .
