## JNaruto5796 2 years ago please helpp mee ): In a geometric sequence, if r=square root of 3 and a4=2,what is the value of a1?

1. satellite73

$$a_1,a_1r,a_1r^2,a_1r^3$$ $a_1r^3=a_4$ $a_1\times 3\sqrt{3}=a_4=2$

2. satellite73

so $a_1=\frac{2}{3\sqrt3}$

Check your question and your approved solution again. Pretty sure satellite73 is spot on. The correct answer might have be simplified to 2sqrt3/9
