Answer:

1st Q- B

2nd Q- A

Step-by-step explanation:

1st Q:

n²<220<(n+1)²

n²<220<(n²+2n+1)

we can plug in the values in the answers and see which one satisfies the inequality:

when n=13 --> 13²<220<(13²+2*13+1) => 169<220<196 (this one does not work)

when n=14 --> 14²<220<(14²+2*14+1) => 196<220<225 (this one works)

when n=15 --> 15²<220<(15²+2*15+1) => 225<220<256 (this one does not work)

when n=16 --> 16²<220<(16²+2*16+1) => 256<220<289 (this one does not work)

so the answer is B

2nd Q:

A
