Answer: -19531250
Step-by-step explanation:
The formula for the nth terms of a geometric or exponential sequence is
nth term = arⁿ ⁻ ¹ , where n = 10th terms, and a = 10
To find the common ratio, we divide the second term by the first term
r = -50/10
= -5
Now substitute for those values in the formula
T₁₀ = 10(-5)¹⁰ ⁻ 1
= 10(-5)⁹
= 10 x -(5)⁹
= 10 x -1953125
= -19,531,250
Therefore the 10th terms of the geometric sequence
= -19531250
