Answer:
aₙ = aₙ₋₁ + n + 1
Step-by-step explanation:
a₁ = 2
a₂ = 2 + 2 + 1 = 5
a₃ = 5 + 3 + 1 = 9
a₄ = 9 + 4 + 1 = 14
a₅ = 14 + 5 + 1 = 20
Six (6) less than (subtraction) six (6) times (multiplication) a number (n) is (=) 12.
6n - 6 = 12
To solve, add 6 to both sides
6n = 18 Dviide both sides by 6
n = 3
24 × 60 = 1,440
1,440 × 90 = 129,600
There are 129,600 pictures in a movie that is 90 minutes long.
