Please note that (a) this is a sequence of square numbes, and (b) the sequence starts at 22.

The numbers are the set of square numbers. Next in the list is 52 = 25.

The most obvious pattern in the sequence 10 30 15 16 48 24 25 is ...*3,/2,+1... The next number in the sequence following the 25 will be 75.

Formula for nth termTn = a + (4n - 1) {where a is the first term and n is natural number}

36 Seems like: 1 4 9 16 25 is squared sequence: 1 2 3 4 5 So 6 squared will be 36.

16/25 is already in its lowest terms

Final sequence:- 1,4,9,16,25,36,49,64,81,100,121,144,169,196… This is a pattern of square numbers. 1^2=1, 2^2=2, 3^2=9, 4^2=16, and 5^2=25. The next number would be 36 because 6^2 equals 36.

This is a sequence based on the squares of numbers (positive integers) but starting with the square of 2. Under normal circumstances the sequence formula would be n2 but as the first term is 4, the sequence formula becomes, (n + 1)2. Check : the third term is (3 + 1)2 = 42 = 16

This is a sequence of perfect squares. 12=1, 22=4, 32=9, 42=16, 52=25. The next number is 62=36.

(n+1)^2 Please tell me you know what that means.

5^n

75The number which best completes the sequence 10 30 15 16 48 24 25 is 75.

The nth term is: 5-6n

75

75

25

They are 25 and 49

10 30 15 16 48 24 25 75...

The next answer in the sequence is 75 The sequence is times 3, divided by 2, plus 1 Example 10*3=30 30/2=15 15+1=16 16*3=48 48/2=24 24+1=25 25*3=75

Ascending terms in the sequence are equal to 12, 32, 52, __, 92, and, for some reason, 102, not 112. Therefore, assuming the last term in the sequence to be 112 = 121, the fourth term in the sequence is 72 = 49.

The next number is 25 but there are the sequence is infinite so there can be no end to the sequence.

It is: 18+7 = 25

Perfect squares.
