Una ONG tiene la finalidad de mejorar las condiciones de salud de personas en estado de pobreza. Si todos los meses se incorporan 5 personas y al final del primer mes hay 125 voluntarios, ¿cuántas personas trabajaran como voluntarios en la ONG al cabo de 2 años y medio?

Step-by-step explanation:

Givens

These problem models a arithmetic sequence, where the difference is 5 and the first term is 125.

Notice that 2 and a half year are equivalent to 18 months. That means we need to find the 18th term,

A arithmetic sequence is defined as

Where , and .

Therefore, after two and a half years, there would be 210 volunteers.

what are ur choices?

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x
