As you can tell, the next time decreases by three every time. So, the tenth term would be -29.
-2,-5,-8,-11,-14,-17,-20,-23,-26,-29
2x + 7 = 3
2x = 3 - 7
2x = -5
x = -5/2
Because SUR=32, then RS must be 32 and because STR=64. You could also tell this because the shape in the circle is not perfectly symmetrical
39781 x 5 = 198905
There are 198905 jelly beans in total:)
