For an Arithmetic Progression,

Sum = 15[a + 7d].{a = first term and d = common difference}

For a Geometric Progression,

Sum = a[1-r^15]/(r-1).{r = common ratio }.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What is the definition for the mathematical term mean?

The arithmetic mean is an average arrived at by adding all the terms together and then dividing by the number of terms. Example : Add the digits up and then divide the sum by the number of separate numbers. For the numbers 2, 4, and 9, the sum is 15 and the mean is 15/3 or 5.

What formula represents the partial sum of the first n terms of the series 5 10 15 20 25?

The series given is an arithmetic progression consisting of 5 terms with a common difference of 5 and first term 5 → sum{n} = (n/2)(2×5 + (n - 1)×5) = n(5n + 5)/2 = 5n(n + 1)/2 As no terms have been given beyond the 5th term, and the series is not stated to be an arithmetic progression, the above formula only holds for n = 1, 2, ..., 5.

What is the sum of the geometric sequence 8comma negative16comma 32 dot dot dot if there are 15 terms?

The sum of a geometric sequence is a(1-rn)/(1-r) In this case, a = 8, r = -2 and n=15 So the sum is 8(1-(-2)15)/(1+2) =8(1+32768)/3 =87,384 So the sum of the first 15 terms of the sequence 8, -16, 32, -64.... is 87,384.


The fourth term of an AP is 15 and the sum of the first 5 terms is 55. Find the first term and the common difference?

x is the first term and d is the difference then x + 3d = 15 and sum of first five terms isx + (x+d) + (x+2d) + (x+3d) + (x+4d)so 5x + 10d = 55 ie x + 2d = 11As x + 3d = 15, d = 4 and x = 3,giving the five terms as 3, 7, 11, 15 and 19

What is the arithmetic mean of the first nine composite numbers that are greater than 10?

To get the arithmetic mean, sum them up and divide by the count (in this case 10). So we have 12 + 14 + 15 + 16 + 18 + 20 + 21 + 22 + 24 + 25 = 187. Divide by 10 is 18.7

What is the sum of 3 plus 7 plus 11 plus 15 plus to 11 terms?

The given sequence is an arithmetic progression with common difference d = 4 and first term a = 3.Sum of n terms of an A.P. is given by: Sn = n/2 x [2a + (n-1)d]We need to find sum of 11 terms so n = 11.Putting value of n, a and d we get:S11 = 11/2 x [2x3 + (11 - 1) x 4]S11 = 11/2 x [6 + 40]S11 = 11/2 x 46 = 11 x 23 = 253


If the seventh term of an arithmetic progression is 15 and th twelfth term is 17.5 find the first term?

There are 5 common differences between seventh and twelfth terms, so the CD is 2.5/5 ie 0.5. First term is therefore 15 - 6 x 0.5 = 12.
