Remember, you take 1/2 of b and square it to get c

c=100
(b/2)^2=c
(b/2)^2=100
sqrt oth sides
b/2=+/-10
times both sides by 2
b=+/-20
it is 20 or -20

First 100 terms of the following sequence 3 ,7 ,11

Sveta_85 [38]

Given that $a_1 = 3, d = 4$

Find the nth term:

$a_n = 3 + 4(n - 1)$

$a_n = 3 + 4n - 4$

$a_n = 4n - 1$

Find the 100th term:

$a_{100} = 4(100) - 1 = 399$

Find the Sum:

$\text{Sum} = 100(\dfrac{a_1 + a_{100}}{2} )= 100 (\dfrac{3 + 399}{2}) = 20100$
