Write the first five terms of the geometric sequence.
-$\mathrm{a}_{1}=7, \mathrm{r}=-7$
A) $7,49,343,2401,16,807$
B) $-49,343,-2401,16,807,-117,649$
C) $7,0,-7,-14,-21$
D) $7,-49,343,-2401,16,807$

Quizplus · Accepted Answer

The first term is 7, and each subsequent term is found by multiplying the previous term by -7. So, the sequence is $7, 7 \times (-7) = -49, -49 \times (-7) = 343, 343 \times (-7) = -2401, -2401 \times (-7) = 16807$.
