Answer:
Explanation:
10,-50,250,-1250,6250,-31250,156250,-781250,39076250,-19531250,97656250,-488281250
Answer is -488,281,250
10*-5=-50
-50*-5=250
250*-5=-1250….until you get -488,281,250
12th term of the geometric sequence is -48,828,125
Step 1: Given details are a = 10, n = 12 and r = a2/a1 = -50/10 = -5
Step 2: Calculate the 12th term of this geometric sequence using the formula a × r^(n-1)
⇒ 12th term = 10 × (-5)^(12 - 1) = 10 × (-5)^11 = -48,828,125
