12th term of the geometric sequence is -48,828,125
Step-by-step explanation:
- 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
