Answer:
549
Step-by-step explanation:
<u>G</u><u>iven </u><u>:</u><u>-</u><u> </u>
- A sequence 4 , 9 , 14 , ...
And we need to find out the 110th term . the given sequence is in Arithmetic progression . So the common difference is 9 -4 = 5 . Now using the formula to find out the nth term of AP ,
<u>Using</u><u> </u><u>formula</u><u> </u><u>:</u><u>-</u><u> </u>
T_n = a + ( n -1)d
T_n = 4 + (110-1)5
T_110 = 4 + 109*5
T_110 = 4 + 545
T_110 = 549 .
<u>Hence </u><u>the </u><u>1</u><u>1</u><u>0</u><u> </u><u>th </u><u>term </u><u>is </u><u>5</u><u>4</u><u>9</u><u> </u><u>.</u>
Answer:
93
Step-by-step explanation:
Line EJ is a straight line, with Line DC cutting through it. So 180 = Angle DCJ + Angle DCE. So Angle DCE = 48. Triangles are equal to 180°. So 180 = ? +39 +48. So ? = 93
