The term to term rule of another sequence is multiply by 2 and add 3 .
the third term of the sequence is 17 what is the first term?

The first term = 2

Step-by-step explanation:

As the term to term rule of another sequence is:

So

if

3rd term =  17                        

then

following this pattern

3rd term = 7×2  +3 = 17

2nd term = 2 ×2 +3 = 7

1st term = -0.5 ×2 +3 = 2
