look at the sequence given in the table. the term number is represented by the x values and the terms are represented by the y values. what is the 25th term of the sequence?

91

Step-by-step explanation:

When x goes from 1 to 2, y increases by 4  from -5 to -1

When x goes from 2 to 3, y increases by 5 from -1 to 3

We are adding 4 each step

The formula for an arithmetic sequence is

an = a1 + d(n-1)

where a1 is the first term a1 =-5

d is the common difference or what we add each time = 4

and n is the term number  n=25

a25 = -5 + 4(25-1)

a25 = -5+4(24)

      -5 +96

    91

The 25th term is 91

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
