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}{()}
