Question

Need help with b and c

Answer 1

Answer:

see explanation

Step-by-step explanation:

We note that for each term, the numerator increases by 1 and the denominator increases by 1 from the previous term, that is

term 1 = $\frac{1+1}{1+2}$ = $\frac{2}{3}$

term 2 = $\frac{2+1}{2+2}$ = $\frac{3}{4}$

term 3 = $\frac{3+1}{3+2}$ = $\frac{4}{5}$

-----------------------------------------------------------------------------

term 100 = $\frac{100+1}{100+2}$ = $\frac{101}{102}$

If we let n be the term value, then the n th term is

$a_{n}$ = $\frac{n+1}{n+2}$

Answer 2

Answer:

Step-by-step explanation:

the formula is:

$a_n = \frac{n+1}{n+2}$

[tex]a_100 = \frac{101}{103}[\tex]
