You need 2 eggs to make 20 cookies. Find out how much cookies one egg makes.

20/2 = 10

1 egg = 10 cookies

now multiply 10 to both sides to find out how much eggs are needed for 100 cookies

1 egg (10) = 10 cookies (10)

1(10) = 10(10)

10 = 100

You need 10 eggs to make 100 cookies

hope this helps

a. First five terms: 9,13,17,21,25

b. Sum of first 25 terms = 1425

c. The given sequence is an arithmetic sequence because the common difference between two consecutive terms is same.

Further explanation:

Given

Formula of sequence

$a_n=4n+5$

1. First 5 terms:

For first 5 terms, we have to put n=1,2,...5,

So,

$For\ n=1\\a_1=4(1)+5\\=4+5\\=9\\For\ n=2\\a_2=4(2)+5\\=8+5\\=13\\For n=3\\a_3=4(3)+5\\=12+5\\=17\\For\ n=4\\a_4= 4(4)+5\\=16+5\\=21\\For\ n=5\\a_5=4(5)+5\\=20+5\\=25\\First\ 5\ terms\ are: 9,13,17,21,25$
