@dpaInc ???

Answer 2

Notice how b_7 = 7+b_6 and b_6 = 6+b_5
So b_7 = 7+6+b_5
Just go on like this until b_1 which is 1.

Answer 3

(sigh) i dont understand :/

Answer 4

Ok so\[\large b_n=n+b_{n-1}\]And b_7 is when n=7 right?

Answer 5

yes i get that part

Answer 6

Good so\[\large b_7=7+b_{7-1}=7+b_6\]right?
