Write an equation for the nth term of the geometric sequence. Then find the 7th term. 2,-6,18,-54,...

Sonja [21]

soln,

from the series,

a = 2

t2 = -6

r = t2/a

$= \frac{ - 6}{2}$

= -3

therefore, tn =

${ar}^{n - 1}$

$= {2 \times - 3}^{n - 1}$

now,

seventh term =

${2 \times - 3}^{7 - 1}$

$= {2 \times - 3}^{6}$

$= 2 \times 729$

$= 1458$

Perform the modular arithmetic. (7 · 15) (mod 4)

Reika [66]

We could do it by first writing

$7\cdot15=(4+3)\cdot(4+11)=4^2+14\cdot4+33$

so that

$7\cdot15\equiv4^2+14\cdot4+33\equiv33\pmod4$

and since $33=32+1=8\cdot4+1$ , we have

$7\cdot15\equiv33\equiv1\pmod4$

# # #

Alternatively, we can just compute the product and take it mod 4:

$7\cdot15=105=104+1=26\cdot4+1$

and so we get the same result of 1.
