<h3>
is the recursive formula of the geometric sequence</h3>
<em><u>Solution:</u></em>
<em><u>Given geometric sequence is:</u></em>
-0.6, 3 , -15, 75
We have to frame the recursive formula
Find the common ratio
Thus common ratio is -5
<em><u>The nth term of geometric sequence is given as:</u></em>
Where,
n is the nth term
a is the first term of sequence
r is common ratio
From sequence,
a = -0.6
r = -5
Therefore,
Where, n = 1 , 2 , 3 , 4 , .....
Thus the recursive formula is found
Answer:
- use the HL postulate
- corresponding angles are congruent; corresponding sides are congruent
Step-by-step explanation:
See below for the marking.
a) Marking the right triangles per the given information, we see that the hypotenuses and one leg are congruent. We can use the HL postulate of congruence to conclude the triangles are congruent.

b) ∆CPS ≅ ∆WPD, so the following parts are congruent:
- ∠C ≅ ∠W
- ∠P (in ∆CPS) ≅ ∠P (in ∆WPD) — these are vertical angles
- ∠S ≅ ∠D
- CP ≅ WP
- PS ≅ PD
- CS ≅ WD
