The first 5 terms for the sequence 3n + 4 would be as follows:
Gather like terms. The - 2 and 4; the 7n and 3n. 7n - 2 + 3n + 4 = 10n + 2
3n+2+3n+2=6n+4
7n - 2 + 3n + 4 = 7n + 3n - 2 + 4 = 10n + 2 which can be simplified to 2(5n +1)
well the first four terms are n=1,2,3 and 4 so just substitute those numbers into k=3n so k= 3,6,9,12
2+3n+2+9n would equal 4+12n after adding all like numbers.
