Its not the first two, I’m having trouble seeing those bottom two and what they are.
3rd one: y=ln x
Answer:
The sum of the arithmetic sequence is
.
Step-by-step explanation:
A sequence is a set of numbers that are in order.
In an arithmetic sequence the difference between one term and the next is a constant. In other words, we just add the same value each time infinitely.
If the first term of an arithmetic sequence is
and the common difference is d, then the nth term of the sequence is given by:

For the sequence

The pattern is continued by adding -11 to the last number each time.
An arithmetic series is the sum of an arithmetic sequence. We find the sum by adding the first,
and last term,
, divide by 2 in order to get the mean of the two values and then multiply by the number of values, <em>n</em>

Answer:
the value of digit 3 in 156.32 =
3 x 0.1 = 0.3
The value of digit 3 in 13 =
3 x 1 = 3
3/0.3=10 times
The value of digit 3 in 13 is 10 ten times the value of digit 3 in 156.32
As long as the (digit in ones/single digit) of a number is equal to 3
The value of digit 3 of it is always 10 ten times the value of digit 3 in 156.32
