1 -> one (3 letters) 7 -> seven (5) 16 -> sixteen (7) 45 -> forty five (9) 79 -> seventy nine (11) 496 -> four ninety six (13)
So next number should have 15 letters i.e. 587 maybe
Ans: 587
(1+7)*2^1=16 (7+16)*2-1^1=45 (45+79)*2^2=496 then (79+496)*2-1^2=1149 so the next no is 1149
Find the number that comes next in the following series:
3, 7, 12, 14, 16, 19, 21, 25, 30, 41, 45, 52, 54, 56, 59, 61, 65, 70, ?
What is the next number in the sequence - 1, 7, 10, 13, 19, 23, 28, 31, 32, 44, 49, 68, 70, 79, 82, 86, 91, 94, 97, 100, 103, 109, 129, 130, ?
