Mathematics
1 answer:
kow [346]3 years ago
7 0

The sequence is

740, 707.60,675.20,642.80,...

Here first term is 740, and common difference, d is

707.60-740 = -32.40

Now we use the formula of nth term, which is

a_{n} = a+(n-1)d

Substituting the values of a,n and d, we will get

=740+(n-1)(-32.40), 23 months

Correct option is the second option .

Helga [31]
There are three options which are the square roots of 100, and those are C. -10, D. 10, and F. |10|
C: (-10)^2 = -10 * -10 = 100 (- * - = +)
D: 10 * 10 = 100
F: |10| = 10, and 10 * 10 = 100 (these brackets make a negative number positive, and a positive number stays positive)
