Answer:
12, 17, 24
Step-by-step explanation:
To find the first 3 terms, substitute n = 1, 2, 3 into the rule, that is
T₁ = 1² + 2(1) + 9 = 1 + 2 + 9 = 12
T₂ = 2² + 2(2) + 9 = 4 + 4 + 9 = 17
T₃ = 3² + 2(3) + 9 = 9 + 6 + 9 = 24
12, 17, 21 is the answer to the question
0.3×1.2
=0.36
−0.3,1.2→Negative
−0.36
it’s C. 0.02,0.2.1/2, 2 1/2
42 batches. 31.5 divided by .75 = 42.
