Vitek1552 [10]

5(x + 3) - 3(x - 2) = 19      That should give you the result you need. The answer will come out to be x = - 1

If you want it to be - 1 to start with, then

2(5x + 3) - 13x + 2 = - 1

Find a formula for the nth term
vlada-n [284]

The formula for a sequence with first term = 1.7 and common difference 0.5 is: a_n = 1.2 + 0.5n

Step-by-step explanation:

The first term and common difference are used to induce a formula for the arithmetic sequence

The explicit formula for a geometric sequence is:

a_n = a_1+(n-1)d

Given

First term = a1 = 1.7

Common Difference = d = 0.5

putting the values in the formula

a_n = 1.7 + (n-1)(0.5)\\a_n = 1.7 + 0.5n-0.5\\a_n = 1.2 + 0.5n

The formula for a sequence with first term = 1.7 and common difference 0.5 is: a_n = 1.2 + 0.5n

Keywords: Arithmetic sequence, Common difference
