Answer:
<h2>
t10 = - 2¹⁹= -524288</h2>
Step-by-step explanation:
t1=2
t2=-8
r=t2/t1=-8/2=-4
t10=t1*r⁹
t10=2*(-4)⁹= -2*(2²)⁹
t10= -2¹⁹= -524288
Answer:
-524288
Step by step
so use the formula
ar^n-1
so
a is first term
r is common ratio
n is number of terms
so
get r which is -8/2=-4
then apply
2×(-4^9)=answer
