Ipatiy [6.2K]

Answer:

a_n = -11-14n

Step-by-step explanation:

Given

a_1 = -25

a_n = a_{n-1}-14

Required

The explicit formula

First, calculate a_2

Set n=2; So:

a_2 = a_{2-1}-14

a_2 = a_{1}-14

Substitute -25 for a_1

a_2 = -25-14

a_2 = -39

Calculate the common difference (d)

d = a_2 - a_1

d = -39 --25

d = -14

So, the nth term is:

a_n = a_1 + (n - 1)d

a_n = -25+ (n - 1)*-14

Open bracket

a_n = -25-14n + 14

Collect like terms

a_n = 14-25-14n

a_n = -11-14n

Please help quick for 25 points with explanations. Any silly and absurd answers will be reported.
amid [387]

Answer:

Note that the tangents to the circles at A and B intersect at a point Z on XY by radical center. Then, since∠ZAB=∠ZQA and ∠ZBA=∠ZQB. ∠AZB+∠AQB=∠AZB+∠ZAB+∠ZBA=180°. ∴ZAQB is cyclic.But if O is the center of w, clearly ZAOB is cyclic with diameter ZO, so ∠ZQO is 90° ⇒Q is the mid-point of XY.Then, by Power of a Point, PY· PX = PA · PB = 15 and it is given that PY+PX = 11. Thus,PX=(11±\sqrt{61})/2. So, PQ=\frac{\sqrt{61} }{2}, PQ²=\frac{61}{4}. Thus, the answer is 61+4=65.
