I would say 2.3 possibly

Step-by-step explanation:
The sequence:
a 1 = 30, a 2 = 70, a 3 = 110, a 4 = 150, a 5 = 190,...
a 2 = a 1 + d
70 = 30 + d
d = 70 - 30 = 40
a n = a 1 + ( n - 1 ) * d
For the 25th month:
a 25 = 30 + 24 * 40 = 30 + 960 = 990
Answer: B ) 990.
This is an example of the commutative property of multiplication.
That property states:

So using that property, we can figure out that
3 should be in the blank.
Example:
38 rounds to 40
6 rounds to 10
10+40 = 50
