Answer:
8
Step-by-step explanation:
Let n represent the number.
2n+3 . . . . "doubled, then increased by 30"
3n -5 . . . . "five less than three times the number"
These two results are equal, so we have ...
2n +3 = 3n -5
8 = n . . . . . . . . . . add 5-2n
The number is 8.

Answer:
19th term = ar^18
19th term = 774,840,978
Step-by-step explanation:
First term, a = 2
Common ratio, r = 3
nth term of a geometric sequence = ar^(n-1)
19th term = ar^(19-1)
19th term = ar^18
= 2 × 3^18
= 2 × 387,420,489
= 774,840,978
19th term = 774,840,978
I think it’d be 2 and 3 if you’re rounding 2.984
