1 5 13 29 61

Next number of the series is 253. So, 125 * 2 + 3 = 250 + 3 = 253. Therefore, 1, 5, 13, 29, 61, 125, 253.So the sequence is 1 5=1+(2×2) 13=5+(4×2) 29= 13+(8×2) 61=29+(16×2)…. so next is 125=61+(32×2) Hence the answer would be 125.The next in the sequence: 5, 13, 29, 61, will be 5,13,29,61. 5, 5×2+3, 13×2+3 29×2+3 61×2+3. 5, 13, 29, 6 125. Next number of the series. The next number in the sequence: 5, 13, 29, 61, will be 125.Find the n term and the sum to n terms of the sequence: (i) 1+5+13+29+61+….
