4n+3
For n = 1, the expression evaluates to 4+3 = 7
For n = 2, the expression evaluates to 8+3 = 11
For n = 3, the expression evaluates to 12+3 = 15
Unless otherwise stated any series/sequence starts with n = 1 Then the first three terms are when n = 1, n= 2 and n = 3 and the series formula 4n - 2 gives the related results, 2, 6 and 10.
4n + 3 = 15 4n +3 - 3 = 15 - 3 4n = 12 4n/4 = 12/4 n = 3

4n-1 = 3
To find the equation of a sequence, you first have to look at the differences between the numbers. In this case the differences are 4, and 4. Thus the equation begins 4n. The sequence minus 4n is: 3, 3, 3 Thus the equation in its entirety is that the value of the term in position n is 4n+3

what is 0 plus 3
4n + 3 = 15 4n +3 - 3 = 15 - 3 4n = 12 4n/4 = 12/4 n = 3
As whole number integers? 4(1) + 1 = 5 ------ 4(2) + 1 = 9 ----- 4(3) + 1 = 13 -------
yes because the + and the - are two terms. hope this helps :3

4n-1 = 3
4n2 + 11n - 3The following method is mathematically correct but may not be taught in school so be careful about using it.Multiply the last term by the coefficient of the first term:4n2 + 11n - 12Reduce the power of n in the first term by one and write them as the first terms in two binomial expressions:(4n )*(4n ).Find 2 factors of the last term (12), and since it is negative, the difference between these two factors should be the middle term (1 and 12). The larger of these takes the same sign as the middle term (so +12) and the other takes the opposite sign (-1).Write these as the second terms in the binomial expressions.(4n +12)*(4n - 1).Finally, divide out the 4 from the first bracket [this is to offset the earlier multiplication by 4] to give the answer:(n + 3)*(4n - 1)

4n-3=5 add 3 both sides 4n=8 divide by 4 both sides n=2
