Answer:
- 1, 3, 7, 11, 15
Step-by-step explanation:
Substitute n = 1, 2, 3, 4, 5 into the rule, that is
a₁ = 4(1) - 5 = 4 - 5 = - 1
a₂ = 4(2) - 5 = 8 - 5 = 3
a₃ = 4(3) - 5 = 12 - 5 = 7
a₄ = 4(4) - 5 = 16 - 5 = 11
a₅ = 4(5) - 5 = 20 - 5 = 15
The first 5 terms are - 1, 3, 7, 11, 15
Angle 3 and angle 4 are supplementary angles and when added together need to equal 180 degrees.
To find angle 4 subtract angle 3 from 180.
Angle 4 = 180 - 101 = 79 degrees.
For every four white balls taken out one black ball is taken out so it would be the 52 white ball
Answer: can't add an answer, but for the first all 3 angles add up to 180 in a triangle for the second, plug 5 in and also check if all three add up to 180
