If the recursive formula is a(n)=a(n-1)+3 and a1=2 then the explicit formula is:

a(n)=2+3(n-1) which simplifies to

a(n)=2+3n-3

a(n)=3n-1 so the first three terms are a(1), a(2), and a(3) which are:

2, 5, and 8

yulyashka [42]

Answer:

Hello

The answer is  30% increase in texts since last month.

IF you feel any problem in understanding , do comment pls.

Step-by-step explanation:

Let

X = last month sent texts

y = this month sent texts

First of all find the no. of increased texts,

by subtracting x from y

=> y-x= 7085- 5450

        = 1635

We want to find these 15 texts % with respect to 5450 texts

i.e.    1635/X

=0.30

for answer in % multiply with 100

i.e. 30%
