What are the values of r and a1 for

The first term a is 3

The common difference is 1/5

Step-by-step explanation:

Here, we want to get the value for the common difference and the first term

The common difference is simply what we have in the bracket

This is 1/5

The initial term can be obtained by substituting the value of 1 for k

Mathematically, we have this as

3(1/5)^(1-1)

= 3(1/5)^0

= 3 * 1 = 3

f

f

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to
