Find the next 3 terms in each sequence <br> 1). 8, 24, 72, 216.... ____, ______, _____,
allochka39001 [22]

Answer: 648, 1,944, and 5,832.

Step-by-step explanation: Begin by studying the pattern.

Here, notice that 8 × 3 is equal to 24.

24 × 3 is equa to 72.

72 × 3 is equal to 216.

Continuing the same pattern, 216 × 3 is equal to 648.

648 × 3 is equal to 1,944.

1,944 × 3 is equal to 5,832.

I have also attached in image below showing my work.

So the three missing terms in the pattern are <em>648</em>, <em>1,944</em>, and <em>5,832</em>.

I = 120 ÷ 840

I = 0.1428 A
