The formula used to find the 99th term in a sequence is a^n = a^1 + (n-1)d. a^1 is the first term, n is the term number we wish to find, and d is the common difference. In order to find d, the pattern in the sequence must be determined. If the sequence begins 1,4,7,10..., then d=3 because there is a difference of 3 between each number. d can be quite simple or more complicated as it can be a function or formula in of itself. However, in the example, a^1=1, n=99, and d=3. The formula then reads a^99 = 1 + (99-1)3. Therefore, a^99 = 295.
The sequence is just each number is the square of 1 to 5 1 squared is 1 2squared is 4 3squared is 9 ect so the 99th number will be 99 squared which is 9801
You first have to figure out some rule for the sequence. This can be quite tricky.
20th term = 20*(20+1)/2
i dont get it
The nth term is Un = a + (n-1)*d where a = U1 is the first term, and d is the common difference.
The 99th term would be a times r to the 98th power ,where a is the first term and r is the common ratio of the terms.
The sequence seems to be calculated by f(n) = 3n + 2.3(1) + 2 = 5, 3(2) + 2 = 8, 3(3) + 2 = 11, and so on.Therefore, the 99th term would be 3(99) + 2 = 299
The sequence is just each number is the square of 1 to 5 1 squared is 1 2squared is 4 3squared is 9 ect so the 99th number will be 99 squared which is 9801
what term is formed by multiplying a term in a sequence by a fixed number to find the next term
a + 99d where 'a' is the first term of the sequence and 'd' is the common difference.
The 90th term of the arithmetic sequence is 461
2 does not have 99 terms!
you must find the pattern of the sequence in order to find the next 50 terms using that pattern and the first part of the sequence given
If the sequence is non-linear, you need to establish how it is defined.
Find the formula of it.
