Step-by-step explanation:
❄️❄️❄️❄️❄️❄️❄️❄️❄️❄️
❄️❄️❄️❄️❄️❄️❄️❄️❄️❄️let a be the 1st term.
❄️❄️❄️❄️❄️❄️❄️❄️❄️❄️let a be the 1st term.Therefore, a=7.
❄️❄️❄️❄️❄️❄️❄️❄️❄️❄️let a be the 1st term.Therefore, a=7.2nd term =a+d
❄️❄️❄️❄️❄️❄️❄️❄️❄️❄️let a be the 1st term.Therefore, a=7.2nd term =a+d 7+d=13
❄️❄️❄️❄️❄️❄️❄️❄️❄️❄️let a be the 1st term.Therefore, a=7.2nd term =a+d 7+d=13d=13-7=6
❄️❄️❄️❄️❄️❄️❄️❄️❄️❄️let a be the 1st term.Therefore, a=7.2nd term =a+d 7+d=13d=13-7=6d=6.
❄️❄️❄️❄️❄️❄️❄️❄️❄️❄️let a be the 1st term.Therefore, a=7.2nd term =a+d 7+d=13d=13-7=6d=6.aⁿ=a+(n-1)d
❄️❄️❄️❄️❄️❄️❄️❄️❄️❄️let a be the 1st term.Therefore, a=7.2nd term =a+d 7+d=13d=13-7=6d=6.aⁿ=a+(n-1)daⁿ=7+(n-1)6
❄️❄️❄️❄️❄️❄️❄️❄️❄️❄️let a be the 1st term.Therefore, a=7.2nd term =a+d 7+d=13d=13-7=6d=6.aⁿ=a+(n-1)daⁿ=7+(n-1)6w.k.t,aⁿ=205
❄️❄️❄️❄️❄️❄️❄️❄️❄️❄️let a be the 1st term.Therefore, a=7.2nd term =a+d 7+d=13d=13-7=6d=6.aⁿ=a+(n-1)daⁿ=7+(n-1)6w.k.t,aⁿ=205therefore,
❄️❄️❄️❄️❄️❄️❄️❄️❄️❄️let a be the 1st term.Therefore, a=7.2nd term =a+d 7+d=13d=13-7=6d=6.aⁿ=a+(n-1)daⁿ=7+(n-1)6w.k.t,aⁿ=205therefore, 205=7+(n-1)6
❄️❄️❄️❄️❄️❄️❄️❄️❄️❄️let a be the 1st term.Therefore, a=7.2nd term =a+d 7+d=13d=13-7=6d=6.aⁿ=a+(n-1)daⁿ=7+(n-1)6w.k.t,aⁿ=205therefore, 205=7+(n-1)6205-7=(n-1)6
❄️❄️❄️❄️❄️❄️❄️❄️❄️❄️let a be the 1st term.Therefore, a=7.2nd term =a+d 7+d=13d=13-7=6d=6.aⁿ=a+(n-1)daⁿ=7+(n-1)6w.k.t,aⁿ=205therefore, 205=7+(n-1)6205-7=(n-1)6198=(n-1)6
❄️❄️❄️❄️❄️❄️❄️❄️❄️❄️let a be the 1st term.Therefore, a=7.2nd term =a+d 7+d=13d=13-7=6d=6.aⁿ=a+(n-1)daⁿ=7+(n-1)6w.k.t,aⁿ=205therefore, 205=7+(n-1)6205-7=(n-1)6198=(n-1)6198/6=(n-1)
❄️❄️❄️❄️❄️❄️❄️❄️❄️❄️let a be the 1st term.Therefore, a=7.2nd term =a+d 7+d=13d=13-7=6d=6.aⁿ=a+(n-1)daⁿ=7+(n-1)6w.k.t,aⁿ=205therefore, 205=7+(n-1)6205-7=(n-1)6198=(n-1)6198/6=(n-1)33=(n-1)
❄️❄️❄️❄️❄️❄️❄️❄️❄️❄️let a be the 1st term.Therefore, a=7.2nd term =a+d 7+d=13d=13-7=6d=6.aⁿ=a+(n-1)daⁿ=7+(n-1)6w.k.t,aⁿ=205therefore, 205=7+(n-1)6205-7=(n-1)6198=(n-1)6198/6=(n-1)33=(n-1)n=33+1=34
❄️❄️❄️❄️❄️❄️❄️❄️❄️❄️let a be the 1st term.Therefore, a=7.2nd term =a+d 7+d=13d=13-7=6d=6.aⁿ=a+(n-1)daⁿ=7+(n-1)6w.k.t,aⁿ=205therefore, 205=7+(n-1)6205-7=(n-1)6198=(n-1)6198/6=(n-1)33=(n-1)n=33+1=34•°• there are 34 terms in the given Arithmetic progression 7,13,19.....205.
