Answer:
- (1) and (3) are correct options
Step-by-step explanation:
- NOT is coded as LKF
- FLY is coded as TNA
<u>Using alphabet, we can see that:</u>
NOT = 14, 15, 20 ⇔ 13+1, 13+2, 13+7 ⇒ LKF = 12,11,6 = 13-1, 13-2, 13-7
Coding for each letter is 13 + x ⇒ 13 - x
(1) TOP ⇒ FKJ
- TOP = 20,15,16 ⇒ 13-7, 13-2, 13-3 = 6,11,10 = FKJ
- Correct
(2) RUN ⇒ IFM
- RUN = 18,21,14 ⇒ 13-5,13-8,13-1 = 8,5,12 = HEL ≠ IFM
- Incorrect
(3) MUG ⇒ MES
- MUG = 13,21,7 ⇒ 13+0, 13-8, 13+6 = 13,5,19 = MES
- Correct
(4) HOT ⇒ RKG
- HOT = 8,15,20 ⇒ 13+5,13-2, 13-7 = 18,11,6 = RKF ≠ RKG
- Incorrect

➷ You need to know these rules to do this:
Two different signs next to each other, make a negative sign
Two signs that are the same, make a plus

An=a1r^(n-1)
given
a5=1/24
a10=1/768
we know that
a5=1/24=a1r^(5-1) and
a10=1/768=a1r^(10-1)
so
1/24=a1r^4
1/768=a1r^9
(a1r^9)/(a1r^4)=r^5=(1/768)/(1/24)=1/32
r^5=1/32
take 5th root of both sides
r=1/2
we have
a5=a1r^4=1/24
evaluate r^4 or (1/2)^4
1/16
a1(1/16)=1/24
times both sides by 16/1
a1=16/24
a1=2/3
the first term is 2/3
