1. Find the common difference and find the 75th term of the arithmetic sequence: 3, 6, 9, 12, ....

Ymorist [56]

Answer:

$\boxed{225}$

Step-by-step explanation:

Arithmetic sequence

$Un = a + (n - 1)b$

First step, find its difference

$b = U_2 - U_1$

$b = 6 - 3$

$b = 3$

So, we get

$a = 3$

$b = 3$

Finally, Let's find the 75th term

$U_{75} = 3 + (75 - 1)3$

$U_{75} = 3 + (74)3$

$U_{75} = 3 + 222$

$U_{75} = 225$
