1. Two = One x 2
Four = Two x 2
Eight = Four x 2
=> The next number is Eight x 2 = Sixteen
2. The next is Seven - Fourteen

Các bạn trả lời giúp mình nhé!
sử dụng phép tính nhanh:
=(one + nine)+(two + eight)+(three + seven)+(four + six)+ten+five
=ten+ten+ten+ten+ten+five
=fifty-five
có số số hạng là:
(10 -1) :1 +1= 10
tổng dãy số là:
(10+1) x 10 :2=45
đáp số :45
