What is the 22nd term of the arithmetic sequence 12 , 17 , 22 , 27 , .... , .... , ....

11Alexandr11 [23.1K]

Answer: 117

Step-by-step explanation:

Formula for arithmetic sequence is:

= a + (n - 1)d

22nd term = a + (n - 1)d

= a + (22 - 1)d = a + 21d

where, a = 12

d = 17 - 12 = 5.

Therefore, 22nd term will be:

= a + 21d

= 12 + 21(5)

= 12 + 105

= 117

The 22nd term is 117

I have some questions that need to be answered fast.<br><br> 1. 42/j = 35/55

Novay_Z [31]

$\frac{42}{j} = \frac{35}{55}$

to solve for j first you need to cross multiply;

j × 35 = 42 × 55

35j = 2,310

j = 2,310 ÷ 35 (did the inverse operation)

j = 66

Hope that helps :D

Please help me with number six

Tpy6a [65]

$w = 2x = 2( \frac{y}{3}) \\ v = 2w = 2 \times 2( \frac{y}{3} ) \\ v + w + x + y = 180 \\ \frac{4}{3} y + \frac{2}{3} y + \frac{y}{3} + y = 180 \\ y( \frac{4}{3} + \frac{2}{3} + \frac{1}{3} + 1) = 180 \\ y = \frac{180}{()}$
