The first four terms are -6, -7, -9 and -13.
Step-by-step explanation:
- Step 1: Given first term, a(1) = -6 and the nth term, a(n) = 2a(n-1) + 5. FInd the first four terms.
⇒ a(1) = -6
⇒ a(2) = 2a(1) + 5 = 2 × -6 + 5 = -12 + 5 = -7
⇒ a(3) = 2a(2) + 5 = 2 × -7 + 5 = -14 + 5 = -9
⇒ a(4) = 2a(3) + 5 = 2 × -9 + 5 = -18 + 5 = -13
Answer:
b) The measure of angle B is 117°.
Step-by-step explanation:
Angles A and C are vertical angles, so are congruent. Angles C and 27° total 90°, so ...
∠C = 90° -27° = 63° . . . . . not 53°
The measure of angle B is the supplement of angle A or C, so is ...
∠B = 180° -∠C = 180° -63°
∠B = 117°
Only choice B is correct.
