First we have to subtract 72 from 604. But we can do it into two steps. Then it makes much easier.
604-72=600+4-70-2=600 +2-70=530+2=532

And now we want to obtain 604 again. But before we calculate it, think what we already did. We subtract 72 from 604 and our result was 532. Now we want back to 604 again, so we have to add 72 to 532. In few steps to do it easier.
532+72= 530 + 2+ 70 + 2= 600 + 4=604

Find the 9th term of the geometric sequence whose common ratio is 1/3 and whose first term is 2.
raketka [301]

Answer:

2/6561

Step-by-step explanation:

Geometric sequence formula : a_n=a_1(r)^n^-^1

where an = nth term, a1 = first term , r = common ratio and n = term position

given ratio : 1/3 , first term : 2 , given this we want to find the 9th term

to do so we simply plug in what we are given into the formula

recall formula : a_n=a_1(r)^n^-^1

define variables : a1 = 2 , r = 1/3 , n = 9

plug in values

a9 = 2(1/3)^(9-1)

subtract exponents

a9 = 2(1/3)^8

evaluate exponent

a9 = 2 (1/6561)

multiply 2 and 1/6561

a9 = 2/6561
