given series is in arithmetic progression
with a=-12 and d=3
sum of n terms of an AP=n/2(2a+(n-1)d)
=>54=n/2(2(-12)+(n-1)3)
=>54=n/2(-24+3n-3)
=>108=n(3n-27)
dividing with 3 on boths sides, we get
=>36=n²-9n
=>n²-9n-36=0
=>n²-12n+3n-36=0
=>n(n-12)+3(n-12)=0
=>(n+3)(n-12)=0
n=12
I hope this will help u :

Answer:
German Volume Training (GVT) is a high-volume approach to hypertrophy training that involves doing 10 sets of 10 repetitions. 10×10. It's like 5×5 strength training except done for twice as many reps and for twice as many sets. The idea is to accumulate more training volume to stimulate more muscle growth.
