What is the next number in the sequence 16 11 13 8 10 5 7?
To find the next number in the sequence 16, 11, 13, 8, 10, 5, 7, we first look for a pattern. Consider the differences between consecutive terms: 11 - 16 = -5 13 - 11 = 2 8 - 13 = -5 10 - 8 = 2 5 - 10 = -5 7 - 5 = 2 The differences alternate between -5 and 2. Following this pattern, the next difference after 7 should be -5: 7 + (-5) = 2 Therefore, the next number in the sequence is **2**.

What is the pattern in 149162536496481?
Square numbers from 1 to 9 OR increasing +2 starting from 3 first. example: 14916.......... 1-4=3 4-9=5 9-16=7 ..... so from 3 to 5 (+2) 5 to 7 (+2)....next is 16+9...+11 +13 +15 +17
