Answer:

1595

Step-by-step explanation:

The given sequence is

2, 7, 26, 101, 400, ?

We need to find the missing term in this pattern.

First term is 2.

a_2=2\times 4-1=8-1=7

a_3=7\times 4-2=28-2=26

a_4=26\times 4-3=104-3=101

a_5=101\times 4-4=404-4=400

So, the nh term of the sequence is

a_n=a_(n-1)\times 4-(n-1)

Substitute n=6,

a_n=a_(6-1)\times 4-(6-1)

a_n=a_(5)\times 4-5

To find the next term, we need to find the product of 400 and 4 and after that the difference of resultant number and 5.

a_6=400\times 4-5=1600-5=1595.

Therefore, the missing term is 1595.

What is 36 percent of 210?
ohaa [14]

Hey there!

Let's start by finding what 1% of 210 is.

This can be done by dividing 210 by 100, since 1% is the same as 1/100 of something.

210 ÷ 100 = 2.1

To find 36%, we can multiply 2.1 by 36.

2.1 x 36 = 75.6

So, 36% of 201 is 75.6.

Hope this helps!

A discrete variable is a variable which may take only certain discrete values; for example the number of people in a household is a discrete variable which may have the value 1, 2, 3, etc. but cannot have intermediate values such as 1.473 or 3.732.
Choice d) can be represented by a discrete probability distribution, the other choices cannot be so represented.
